So I e recently come to find out that my girlfriend of 6 years has cheated on me with a guy who frequents her work. She confessed only after I found txt messages from his stating some inappropriate things. I have forgiven her, but my trust is shaken. She tells me she loves me and that she wants to be together, but she didn't want to break off the friendship with him. He is much older than her and its obvious that he's using her. I told her she needs to cut all toes but she is finding it so hard. It's becoming emotionally taxing and nerve wracking, because she just can't seem to give up their friendship. I finally gave her the ultimatum it's him or me, she chose to stop talking to him, but now she just seems angry at me and is sad all the time. I'm just sure what too feel because I love her so much and I can't be positive she loves me and not him. I don't know what to do anymore and I feel myself being crushed under uncertainty.
