Need advise

Flower99- i think i did it.

Thanks everyone for your advise. It's going to be tough but i know what i have to do. flower99... i would like to hear what you have to say but i'm new to this and i'm not sure how to go about private messaging.

I am pretty sure that he hasn't cheated. He just doesn't trust me at all.

My boyfriend and I have been together for 5 years. Lately he has been accusing me cheating of on him. He is so sure, that I cheated on him. Everyday for the past 3 months he insists that I tell him the truth. I never cheated on him..ever! He's really into trust…one time he asked me if I have any guy friends at work and, since I want to be completely honest with him, I told him that I did. What was that for… He had a fit. He started asking me 21 questions, which eventually got annoying. I was then kicking myself for opening my mouth to begin with. At this point, I was so upset that I didn't even want to talk to him anymore. He asked me who was more important between him and my co-worker and I refused to answer. Of course my boyfriend is, without a doubt, more important but just the fact that I even had to answer that pissed me off, so I did not answer. It just got worst from there. It got violent until I gave in and said he was. He said that I took to long to answer and that it shouldn't have been hard for me to answer. Which it wasn't..it was just his temper that pissed me off and in the manner that he was asking me, like I was suppose to be scared or something. I am really proud and stubborn and my pride did not let me budge until the end when it too much. After that night, we talked when we were both calm. We both really tried to resolve this issue but he just don't know how to let things go and he starts asking me to do stupid things like prove that I am not cheating, and he wanted me not to talk to my co-worker ever again (which is impossible because we work together)..and around this time I start to loose my patience again and the argument begins again. Not one day goes by where he doesn't ask me how my co-worker is doing. He tells me that he know we did something. He's threaten to come to my job and look for the guy. He's threaten to call the job and curse him out. And the poor guy from work does not have a clue what's going on. I don't even talk to him like that. I have even distance myself from this guy. My coworker is actually married and I told my boyfriend this but that just gets him more mad. He tells me that a guy is a guy no matter what. We both want to work things out but he says he needs closure with this situation and he does not have it. He tells me to prove it to him that I am not cheating but I don't know how to do that and at this point, I'm just fed up with it. I love him so much and I know he loves me too but the trust is way gone. He is too jealous. I know that he tries to change but he cannot seem to let this go. It is not always bad. When it good its great but when it's bad.. it's really bad. We both have lost respect for each other with the name-calling and the hands. I sometimes feel that he brings the crazy out of me. I have lost all my friends ever since I been with him. He is all I have. I don't know what to do.. I'm so worn out. I just don't feel like I have it in me to fight for this relationship anymore. Please..need some advise.
