I just found this site and I think it's helped me. Here's my story

My girlfriend of nearly one year cheatedcheated on me with my former real good friend.I had just picked my former bud up from work, he was letting me and her stay with him at his house for a while until we got up on our feet. we had been there about a month and a half maybe 2 months, and for a while me and my girlfriend were happy then about 3 weeks ago we started having problems. I have Low T, I've been depressed about not being able to support her and us not having much income, which severely crushed my sex drive and made me even deny sex multiple times. I was unfortunately working out of town until I could be transferred over to a closer location so I had to stay out of town, with her mom mind you, for 4 days at a time, but it was my last week up there, the transfer had gone through, I only had to work 2 days then I could go back and be with my girlfriend. During these two days, after about 3 weeks of not having sex, she cheated on me. I came back home and I could feel tensions were high but I played it off and kicked it like usual. I started noticing that her and another roomates were always at near vicious odds, when they used to be playfully mean.I didn't ask, I just figured one of their jokes went too far. Turns out he had heard her cheating on me with the household leader. Apparently her noises woke him up and he noticed that one of the rooms was locked. 

Weeks went on and he springs a trip on me begging me to take him 300 miles to go see his long distance girlfriend he paid me of course. So I ask my girlfriend to use her jeep, knowing that my car is less dependable and in no way is ready for a 600 mile road trip. She agreed, I had to go without her because she was in the process of getting hired to a good job in town so I reluctantly left her and set on about the trip. On the way back the roomates is just going on and on about how shirt of a person my girlfriend is and that I deserve better, now mind you me and her had been fighting on/off a week prior until I kinda got my drive back and we got back in the sack. I told him that me and her were getting better, but he kept saying off things about her (to my ears). Now back to 3 days ago. 

I had just picked up my bud (head of household) from work and brought him home,  my girlfriend was away at work and the other roomate was staying with his sister for a couple days. It was just me and him. When we got to the house he went about making breakfast for me and him, we played some black ops 3 and after about an hour of playing her turned the system off and sat in silence. When I asked him what was going on he told me that he couldn't do it anymore, bust into tears and told me what he had done. I punched him in his face and he urged me to talk to him more before doing anything rash so I did. I can't remember what he said, I was too drunk on rage to remember. But in the end I passed out. I was awoken by my girlfriend on her lunch break, happy to see me, totally unaware of my conversation with the head of house. I couldn't talk. It took her going to leave for me to confront her. We yelled at each other for a good while after that, I even dropped her back off at work so that I could keep yelling my rage unto her. Then I sat there. I picked her up after work and began yelling at her again. I had to go to work now, so I drove to my work told her to sit in the car and think while I went in. I came back out on my break. We talked for a good long while, so long that I even got in trouble yesterday for taking such a long break. After work I had her drive. We went somewhere totally secluded from the world and kept talking. After discussing everything about this month that has happened so far and about our relationship. I came to a decision to stay with her. 

Trust me I know alright you don't need to comment "oh you're just giving her power now she can do it again and again without fear of losing you because you forgave her once you'll forgive her again and you'll die inside every day" trust me I know. She has been the Only one I've made this decision about. I've been cheated on 6 times now and every girl before her I have dropped and never even reconsidered them as a sentient being ever again.  But yeah I decided to stay with her, by no means does that mean I've forgiven her,nor do I trust her anymore. But she is willing to make up for it any b means necessary. Needless to say I've been testing that and thus far She has been successful. Me and her have since left my former friends house and are moving into an apartment tomorrow. I'm not asking for advice just what you think. I love her and she is willing to do anything for me to earn back my trust and  has thus far.
