I've been with my fiancé, now for 3yrs and about 3 months ago I found out that he cheated on me with his best friends wife his best friend and his wife had been separated for 2 months. My fiancé, claims that because, I was working 2nd shift until 1am and he was home drinking and he had no work at that time he was sad and lonely and his best friends wife had IM him and challenged him that he was scared to come over, because he was scared of her husband.He said that he had drove straight over to her apartment and she had put her 4 kids to sleep early. They did the deed and he said he came straight home.The next day she called her husbands family and her husband and told everyone what had happened and she was crying and had felt guilty. I had just got home from my 2nd job which was a morning job and I had answered the phone and it was his best-friend and he had said that my fiancé had cheated on me with his wife and that it's not the first time.His best friend had said that my fiancé had cheated on me a bunch of times and that I just didn't want to believe it because I was in love. At first I was defending him (for about 20 min)..I at first was thinking wow, she went too far trying to hurt her husband and make up lies...Yeah that didn't last too long. His friend then told me he knows his wife and she's not lying and that he knows my fiancé better than anyone and he has been an A-hole to me and that this was the last straw and I needed to know. I asked my fiancé about it and he denied it until I left and said I was going to the store.well, I went to her house and she just started crying and saying its true and how sorry she was, I my fiancé had called while I was over there and he sounded so low and sad, I told him we'll talk. When I got to the house he had confessed to everything and said he didn't mean to hurt me and loves me so much and won't ever do it again and everyday since he will just stop and cry out of no where while he's looking at me and just say he's so sorry for hurting me.I think about it at some point everyday. I love this man so much and more than anything I know...We had been on top of the world(well at least I was) and someone had told me that sometimes we can be so caught up in the fantasy of thing and bright lights that we're blinded by what is really in front of us...He tells me everyday he wants to work it out and get counseling and do anything to make it better..But we're now arguing about little things..He is my first, boyfriend minus the one or two I had in 1st grade.I really need to know what to do I'm going crazy thinking of all the times I haven't been home and if there had been others. It was just too easy for him to do it and it has me scared. Plus, they didn't even have enough respect to use protection. And that left me even more livid!HELP! I need some advice on where to go and what to do...Like I said My first boyfriend I feel like I don't know how to handle it.
