We have liked each other for a couple years but never knew about the mutual affection, we thought it was one way. Then, when I was dating someone else she admitted that she liked me and I admitted that I used to like her. After a bad break up with that other girl, I told the first one that I still liked her and that she liked me. I had my chance to date her and I said no because of what just happened with the other relationship. I am now over it but now she has a boyfriend. The other day my good friend told me I should go for her because he could tell that we liked each other by just looking at us (I never told him that I liked her). I just don't know if I should go after her and make her happier with me than her current boyfriend in order for her to date me. What should I do?
