What is she thinking?

I am in love with my best friend. She has had a hard couple of years. 2 years ago she was happily married to the man of her dreams, her first love. They had ond son and another on the way. The perfict family. Than things changed one afternoon. They had an automible acident and he died along with there unborn child. I had known her for several years before this, but hadn’t seen her but just a couple of times since she married. About 2 months after the wreck we end up working the same youth camp( the one where we had meet) and we reconnected. That was about a year and 4 months ago after that we talked a few times but that was it. Until about 6 months ago she broke up with the guy she had been seeing and we started talking on a daily basies. Then we got to see each other one night a couple of months later. Things just started coming together for us since then. I got to go up and spend the evening with her about 6 weeks ago and we had an awesome time. She drove me out to the lake and we watched the stars and there was alot of fallen stars that evening we ended up spending about 3 hours out there ineach others arms and had our first kiss that night. Since then we have seen each other almot everyweekend. Last weekend was a little different though. She has a band and her drummer couldn’t make the gig that night so her ex-boyfriend played for her. I noticed that she was giving him alot of attenchen but didn’t give it much thought. That night after he left and we were alone at her place it was all about us agian. After I left though I got to thinking about it. Since we have never made the move to call ourselfs any thing but friends I ask her later if her and him were getting back together and she said she didn’t know she was thinking about it. What di I do I am in so much love with her I can’t stand the thought of not being around her and her in my arms.
