Since I'm single, and I have feelings like I have to have a significant other, I've been taking a look at this girl. I hang out with her everyday, but I don't know if she likes me. We had a thing last year, but then she started dating this other guy. The guy is my best friend and he lives with her. He knows we had a thing. What I'm wondering is, how would I know if she likes me. The thing is, they fight like everyday. I feel like I could be a much better boyfriend to her, and we have a lot more in common. He's leaving for the air force in a couple months, and I'm wondering if I should bother going for her. How would I know if she likes me, and should I go for her when her boyfriend leaves? I really like her and have since we had a little thing.
