Hi. I really need advice on how to deal with infidelity. I found out my fiance cheated on me last week whilst on a business trip. I found a girl's t-shirt in his suitcase and eventually confronted him - after initial denials and lies, he admitted he'd 'kissed' somebody else. It turned out that in fact he'd gone back to his hotel room with her where they fooled around and fell asleep. I don't know whether or not to believe this, my head tells me not to, though somehow I do anyway. I am completely devasted though and don't know how to deal with this nightmare and what to do now. I love him so much and feel so betrayed. All our plans are now shattered and I have no idea how to proceed. If I were outside of this situation I would advise to leave him straight away, but since it's happening to me, I am finding it so so difficult to make that decision. In fact I want to stay with him but I just don't know how to get over this. He has said all the right things, says he is devasted with what he has done and doesn't know why he did it. Can relationships survive after this? Will he do it again? Help. I'm so sad.
