I guess the best thing i did for my girlfriend was actually singing her a song when we had a graduation practice. I gave her a shout out and she start to blush so i think that was the best thing i ever did.

I bought her a wind chime that cost me £100 that was the best thing i gave her
the best memory i gave her was when i was singing Ride on time by black box

In my short relationship, I treated my ex to a nice little dinner that cost like $70. I put in all I had for it, and she dumped me anyways.

My boyfriend and I have done so many things for each other, it's hard to choose. Well I guess the best present I gave him was a nerf gun for Christmas. Granted he already had that one(after I had stood in Walmart for 10 minutes trying to figure out which of the two he already had)but he was so happy that I at least tried and told everyone how his girlfriend had bought him a nerf gun.

HOLY THREAD BUMPS, BATMAN!

Sorry, but I have to do that every time I find a thread I wanna bump .

Now on to the REAL topic!

I'm not really sure, you'd have to ask her that . However, if I'd have to guess, I think one of the best things I've done was actually what drove me to ask her out. We were at church camp this summer (how I really got to know her, too) and it was the last full day. We were leaving the next morning before the closing ceremony so we could get back at a reasonable time (the camp was a good 10-hour drive without stops for lunch and dinner), and her family was heading back down south for vacation in Florida, so she wasn't sure when she was leaving. So, she's already stressed, and on top of that, the sermon that night was about reaching out to people who you've hurt and who have hurt you. Long story short, her relationship with her birth mother is...less than pleasant, and she's also said some things about her step mother that she regrets. So after the sermon it's all just piled up on her and as we stand to sing she's crying, so I did the first thing that popped into my head: I wrapped my arm around her and held her as we sang, doing my best to comfort her. She confessed to me later that part of the reason she realized how she felt for me was that I was there for her throughout the week and especially that night.

So yeah, sentimental touch there .

The best thing I've done for my girlfriend is be there for her every single time, while she was down. I always try to help her when she's down.
