How to Cure Insecurity

I am 28 and planning a wedding to the man of my dreams. We have been together almost two years, living together for one, and have the relationship I always dreamed of but never thought I would have. I have always had problems with depression and low self-esteem and it is showing itself in my relationship now as insecurity.

I trust my fiancé and have no problem with us doing things separately, we just got back from separate vacations (I went on a road trip with my sister and he went to the West Coast to visit his two best friends). I was looking on Facebook today, and his friend posted some pictures and one of my fiance's ex-flings had commented on a picture of him saying how great he looked and how much she missed all of them.

My fiancé isn't on Facebook so it's not like she was even talking directly to him but it still made me feel awful and I just don't understand why. I am a little touchy about this girl in particular because she has tried to reach out to him a lot since we have been together and he cheated on his last girlfriend with her. I just wish I could let it go and stop feeling insecure about his past. My best friend told me that insecurity somehow magically disappears when you get married, but I have a hard time believing that.

I think part of my problem is that I have always dated crappy guys in the past, and now that I am with someone who treats me well I almost feel like I don't deserve it. I constantly find myself comparing myself to his ex girlfriends and wondering if he is still thinking about them. I really want to move past this issue so I can be completely comfortable and happy in this relationship . . . can anyone relate? What can I do? I have been working out a lot and eating well lately to get in shape for the wedding and I think that is helping some. I have friends that I hang out with on my own and hobbies that I enjoy, it's really just a mental thing that has always been with me. Any advice would be welcome!
