My marriage has been pretty rocky ever since I had my son two years ago. I do love my DH but things have not been great, he never wants sex with me anymore - he says he finds it hard to think about me in that way since he saw me give birth. I have been feeling so low and lost all my confidence. Recently I have been very attracted to a man at work. He is lovely and we get on so well and he makes me feel attractive again. He is in a relationship but not married. We have had a couple of kisses and cuddles but apart from that just flirting and then a few nights ago we had to go away on a conference aand ended up sleeping together. I feel so dreadful about it now and cannot believe I have been unfaithful and it has made me realise how much I do still love my DH. I want to blame the other guy for this happening but to be honest it was my instigation which makes things even worse. I feel so dreadful just don't know what to do - can anyone help?
