I'm new to this site and I am looking for some good advice.
My gf and i have been together for over five years now and she still does not trust me. For some reason she thinks i am going to leave her for a man one day even though i am a total lesbian. Three years ago she cheated on me with her best friend at the time. When i asked her why she did it, her response was because she thought i was cheating on her. Our relationship is hurting because of this jealousy. I have absolutely no friends because whenever i take an interest in someone (purely platonic!!) she accuses me of cheating.
I started going to college and i cant even talk about people in my classes because her first response is "Do you like them? Is she pretty?" I have no social life but she is free to have her own friends.
Lately, i've been feeling that I want to cheat. Just so her accusations would be true for once. I'm not that type of person and im am completely losing my mind over it. However, if a girl started showing an interest in me now, i dont know if i could refuse.
What should i do?
