So I know these get posted all the time but here it goes. I have been dating this girl for coming up on 3 years. We now both work full time and live together. Well in the past few months she has been very distant and fighting over little things for no reason. Well we just had a huge fight and come to find out that she "doesn't feel the same". She says that i have been neglecting her and not paying as much attention as i should and that i need to spend more time with her family cause they think i don't like them. Well i have been suspecting that she had been talking to someone. She would always ask me if she could go out with her friends and no i find out she has been "talking" to this guy and hanging out with him when hes at work or hes at his firehouse without telling me. A friend who works with him comes to tell me the other day that he had walked into work and said guy said to him "you dimed me out that i was talking to her". I confronted him on the phone and he said that nothing happened and that he had no intrest in more then just a friend with her. Well after that I confront her and she says that she had been interested in him. And also this guy is friends with her brother. Now she needs times to think about things and I just don't know what i should do. I want to fix the things that i did wrong but the fact that she was interested in him (and im not sure if anything happened) is eating me alive inside. I had to leave work sick because i felt like i was going to puke thinking about this. I know some of this may not make sense and im sure im missing things but i just wanted to get this out there because its making me sick.
