Any suggestions?

I'll try to keep this as short as possible. I'm trying to figure out a way to get my ex back. We dated for 8 years with a few break ups in between with the longest only being 4 months. The break ups were over several different things but for the most part it was all kid stuff. We met very young and dated well into our 20s. I haven't been with her for almost 2 years now and have dated several women since but I can never seem to make a connection with them and I am always drawn back to her. I'm good friends with her brother and see her every once in a while. We have been friendly when we do make contact. As of recently we have been chatting online, I've kept it pretty light. The other night we actually hung out for the first time since our break up with her brother and his girlfriend. It was a bit weird at first but at the same time it felt so natural. I have been suppressing feelings for her for a while now but since we've hung around I can't get her out of my head. I really want her back and I'm not sure if it is possible. I don't want to pressure her and I know she is afraid of getting hurt again but, I know for sure that she is the woman I want to spend the rest of my life with. I know this with out a shadow of a doubt. Our break up was mutual and we both kind of saw it coming when it happened. I did however, try to get her back about 6 months ago. She said she needed to get some things together in her life such as a new career. She got a new job some time ago now and I know, from her brother, that she hasn't had much luck with guys either. When I talk to her I'm having a hard time getting a read on her. I don't know what to expect. I don't want to push her away but at the same time I feel I need to fight for what I want. Any advice on how I could possibly approach this delicate situation?
