I know she wouldn't cheat on me nor has she ever given me a reason to suspect her otherwise. Every time she goes out in public without me, I constantly worry about her getting picked up by men or flaunting herself around. The thing is, almost every GF or woman i've dated before her has betrayed me in some way. This has left me jaded and very untrusting of women in general. With those odds, I feel as though any woman who will come into my life will be destined to cheat on me. It's not a matter of if she will cheat, but when The first one who ever cheated on me (6 years ago) left the deepest of wounds and I don't know how to get over this constant betrayal paranoia. I went to a shrink, went on Lexapro, did a lot of reading online regarding the subject and have tried very hard to improve upon my character and overcome this fear. I talk with my GF a lot about this and she's very understanding and reassuring, but for some reason it isn't helping me. I don't really know how to make this fear go away. I want to be able to relax and just enjoy the wonderful relationship that I have with my girlfriend. I want to propose to her, but I don't feel that it's fair to her because of this.
