I never thought I would ever be in this situation ever again in my life...I'm 28 shes 27 and I've been with this girl since I was 17 years old...I was truely faithful to her which makes it that much harder...this girl was my everything....I wanted everything with this girl..marriage kids the whole shabang...Now all that is gone and I feel so empty and confused...Did I do something wrong? Could I have done something to prevent this? Am I not the guy I wanted to be? These are the ?s im drilling myself EVERYDAY and EVERY Night....Heres the backstory...3 yrs ago she cheated on me with her friend....we worked it out nd continued our relationship...yr later she leaves me and come to find out she was w this guy she cheated on me with...6 months later we get back together...After we got back together she told me that shes changed and she wants to focus on US and thats it..she even mentioned about us getting married (which is funny cause i was the one that wanted to marry her and she was the one that didnt want to, I proposed to her a yr before she cheated on me, and sometimes she wouldnt even wear the ring)...But I decided to wait due to us just getting back together...Everything was GREAT...I had the love of my life back and nothing was going to break us up ever...our bond was that much stronger...so the next 2-3 yrs I didnt have 1 complaint...and the best part was she barely went out to bars..she used to go every fri night and sat night and that went down to once every 2-3 weeks...She seemed committed...BUT now ever since her friend broke up with her bf her friend (who is 35 and has 3 kids) wants to go out every fri and sat EVERY WEEK..and strings my gf along...Now once every 2-3 weeks turned into every fri and sat night...(and when they go out, they go out to the bar that the guy she cheated on me with goes every weekend)...Then I started getting a weird feeling 2 months ago..like somethings up...No sex, feeling that shes distancing herself from me, no affection NOTHING...Everytime I would go out w friends and their gfs to shoot pool she would rather go out with her girlfriends then me...So i felt alittle uneasy about that whole situation..so my curiousity kicked in and i looked in her phone and what do I see..a picture of her and the guy she cheated on me with on her phone...i was so livid and confronted her and she said she will try and stop going to bars...she even asked her mom.."did i lose rob, is it too late" she seemed worried..but I FORGAVE HER...then 3 weeks later my buddy texts me that he sees her hanging with this guy here and there at the bar and talks to him...i confronted her and all she says is that she talks to everyone..then last week my buddy broke the news and said he saw her and her friend with this guy ALL NIGHT this time..they walked in together and walked out....So this devastated me since I gave her sooo many chances...I told her too move out because on how livid i was..but after a few days the guilt started to pour down on me...She said she doesnt want to live with someone thats sad all the time..(granted ive been sad due to all this stuff happeneing) .Sorry for so long I am just so depressed....she doesnt even show that she cares or wants to work on this..she just doesnt care...we have a beautiful house, awesome dogs, and thought we had a great life together...not only is she the love of my life but shes my best friend ...The agony is killing me...I feel like I will never feel like this again nor find someone..I feel so insecure about myself....
