What will happen?

I am best friends with a girl named Gina. Me and her are real close, and can tell each other anything. We had dated previously a year and a half back, but recently I realized that not only do I have feelings for her, they have progressed. She has a boyfriend as of now, and they've been dating since a little after me and her broke up. She said she is getting tired of him in some ways, but she says she is in love with the kid. My problem is that I fall for her the more I see and talk to her. We connect on so many levels, and that I think that we are meant for each other at this stage in life. Although we are three years apart, that doesnt' seem to matter because her maturity level is of an 18 year old. She tells me she can be in a bad mood but I always make her smile by just talking to her. She knows that I am kinda jealous of her b/f, as her b/f feels threatened by me because of our friendship, kinda controlling. Her mother can't stand him, and thinks that I am more suitable for her. She kinda knows that I still have feelings for her, and I think she still has feelings for me. My question is, what are her feelings of me? What will happen in the coming future with us whether if it's just being best friends, or being a couple? My d.o.b is 9/16/85, her d.o.b is 9/29/88. Thanks so much, and god bless.
