Cheating sucks. Whether it was you or he other who did it it takes two to cheat. Warmaker is right about the fact that if someone is cheating on you that mean something is missing from you. Sometimes though, it isn't just you who is missing something though. Like I said it takes two - to make a mistake and purposefully commit acts that is not beneficial to your relationship - to make or break a relationship. 

Thankfully I have never cheated, I have a wild mind, mind you, but I am always in control of one variable and that is myself. I can only control myself. I have never cheated but I have been cheated on. Really showed me what I lacked. Why was I inadequate? First, blame yourself, see if you are at fault, truly and really, were you? Why do I have a wild mind? It takes two. Clearly something is missing on her part if I am actively thinking of other chicks and clearly something is wrong with me if she finds another guy more attractive even if he is less built and is unintelligent right? So it comes down to both persons. 

I think everything needs a balance. You be there for her and she will for you. You let things get stale and in time she will find you stale and vice versa. I just suggest a few things and explain them to the people here who wouldn't know how to deal with such a situation.

1. Do not cheat. Break up first. If you cheat and get with your new partner that relationship is likely to end the same way: someone cheating.
2. Relationship going stale? Go climb a mountain, Go parasailing, go do something you normally wouldn't do...all with your partner
3. Be fit - yes it is superficial but people choose mates that are healthy looking, strong looking, in other words, you need to be a strong man or a tender woman who is strong in her own rights. This kind of stuff really starts in high school but it is never too late to stop drinking soda right?
4. Be an organized person. If you are hurt how do you cope? You need to find a way to cope, it can be different for everyone. I personally found a little time every day to cry in the shower after letting people know and them telling me to not be too sad blah blah and I found new things to do, kept myself busy.
5. Piggybacking on #4, After you are hurt, you need to keep your life going whether you take this person back or not.
6. IF you are the cheater, you are a straightup a**h*** if you don't feel guilt. If you cheated and feel that the relationship has to end, DO IT. It saves everyone time, money, and pain only humans can experience. 

There is certainly more, but I need to go get a few games of Mario Kart in before she wakes up...So good look everyone. This is a tough subject but it is certainly not an endless one. There are so many ways to go wrong because there are so many interesting and beautiful people everywhere, it can be hard not to stray but like I use self control to stop things. It isn't that hard. The hard part is if you were cheated on, you need to cope somehow. 

To the poor souls who has never been in a relationship: it is a fun thing but also very stressful. I say poor souls because you really do not know what you are missing unless you are kids then take it easy. Have a few high school flings, that is like training for the blissful brutality that is to come later on because now $$$ is involved. Believe it or not, money cannot buy love but it is a really big part of life in general and it can be an obstacle if you are lacking too much in it.

In all honesty, being cheated on can be seen as a positive. Then you know what signs to look for, who not to trust, and it pushes you one step closer to the guy/girl that will treat you like their only for the simple fact that you are their only. You will find the one (because the one is real) and you will forget all about the others that were in your life. When you find love you feel something but when you find true love you feel something greater. If you fell the same way about multiple people, then they are not the right one for you.

I have been cheated on, by my most recent girlfriend. I saw her on other social media sites saying stuff to other boys like "I Love You", and calling each other couple names, and hugging & kissing, and I was mad as pants(tryna say something else there).  There were no mentions of me, and how she loved me. She told me she loved me a lot, but after seeing all that, i dont think she meant it at all. I really hate cheaters and cheating.

I haven't been cheated on myself, but i have cheated on my girlfriend once. She was ignoring me, so i opted to spite her. I made out with another girl and had word of that spread all over. We broke up after and i found a girl who actually loved me.

Thank goodness I have never been in any part of the cheating process whatsoever. It can have its negative effects one side or both depending on where one stands.

However, the experience and comprehension you get from it, will give you the wisdom to learn from it and you will know what to do next time in your next relationship. This sort of situation can be rather tricky and sticky but if you have the guts and emotion to move on with your life, you can do so much better in the future and learn from your mistakes and future similar situations if possible.

Yes i have been cheated on before, It's honestly not something that i took personally, They tried to apologise and seemed regretful of the incident so i forgave them.. Sometimes these things can happen in relationships... And you just have to trust that person despite what they did... I feel that if you can do that then you truly love someone... 

If someone cheats on you i don't think you'll particularly learn anything from that experience to prevent it from happening again.. After all none of us have the ability to predict and stop others from doing what they do..... We just have to show how much we love and respect them and hope they return that love and respect back....

Yes one way is to say that you can do better in the future... But if you truly loved that person then there's not much improvement you can find in a relationship... That's all..

I have yet to be in a serious relationship and I doubt that I would ever even consider cheating on someone because I would at least have the decency to break up with them first, and even then, going out with people back to back doesn't look good, at least in my opinion. I don't really plan to start dating anyone until college, or even after college...I feel that high school dating is really just practice for those that do it because let's face it, the majority of high school relationships are trivial and they really don't last longer than a 10 minute shower it seems....I'm hoping that by the time I reach college, and even afterward, that the people in my age range will be more mature and won't succumb to cheating to the degree that is found in high school. In the end though, cheating is like second nature for some people, and it is just a way of life...and that is where karma comes into play. Hopefully I pick someone that is honest and open when it comes to relationship type things.
