Should I get a good friend a valentine's day gift because she didn't receive one?

Yes, send it, but with a card making your intentions clear so you won't get unnecessary jealousy from her boyfriend!

I think that's very sweet and I think you should do it. Hey you guys are friends right so its ok. Have some suggestion though. You should send her a yellow and red flowers friendship and love. And think that's very sweet. And hey I don't think its too late so do it soon.
oh and probably add like a funny late valentine card. That should do. Good luck.

The fact that it is bothering you this much, yes you should! I'm not sure how you really feel about this girl. If you do like her, then there are no consequences whatsoever. You're friends, and you are a nice guy, so that's awesome. If you like her just as a friend, you should still do it, but you just have to make sure that she knows that it's just because you're good friends.

But either way, that would be awesome if you did it. Do it to her workplace, so all of her coworkers see it, and it will really make her day awesome, and make her feel like she's on cloud 9. It also shows her that great guys do exist, and even if you two aren't to be together, it will show her that she deserves someone better then her current boyfriend.
