Getting over trust issues?
So long story short, girlfriend and I were together for almost 7 years. She cheated on me once and I took her back. Three years later (a few weeks ago) we realized that we were not a match for each other (thoughts of infidelity in her head) and both of us were basically unhappy, so we broke it off.
We are both still living together until we can find places for us to move out on our own. There is also a guy friend from her work that she sends text messages to like crazy (50-80 a day, although all of the messages are essentially innocuous. This is also the guy she admitted having REALLY strong feelings for and where her toughts of infidelity came back in. This is driving me crazy... mainly because of the quantity of contact, almost like it was so easy for her to find someone to fill my role and talk about stuff with. Also this guy from work has a relationship and I feel like she is being really selfish to continue to contact this guy when he already has a relationship.
Due to her previous infidelity and this new guy (even though we are broken up) I seem to want to know everything that is going on in her head. I have asked her to see the text messages just to ease my mind and she has accepted, but I really do not want that. I want to not care or have the desire to know everything she is doing.
I realize that I never really got over her first instance of infidelity and then with this new guy I feel like it is happening all over again (yes I realize we are really broken up).
How can I get myself to not care who she is contacting or what she is really thinking and just let her live her new life. Or will this not really happen until we both move out? I feel like even then I will still have this desire to see how quickly she fills my place...
I want to be normal again...
