Please help, I cant recover from my live in boyfriends affair. We have been together for over a year and a half and both have children from previous marriages. I found out after catching and cornering my boyfriend that he has engaged in a 4 week affair with his exwife. I am fully aware that neither my boyfriend or his exwife wants to be together but I think they were both needing attention in some way. He is now begging to be forgiven and promises to never stray again but I am having such a hard time putting this behind us. I love him so very much and I want to move forward and share our future together but how am I able to not resent him? Should I assume that since he had done this once that he will continue? His exwife hates me so I am positive she will pursue him again if nothing more than to attempt to ruin our relationship. This hurts so terribly and so deeply and just wish to turn back time so my boyfriend wouldnt have been so stupid and weak. Problem is just getting worse for me because everytime I close my eyes all I do is think of his deception and the two of them together. Is this worth saving after a year and a half or do I walk away?
