Background: I am 42, DH is 44, we have been married for 15 years having known each other for over 20, and have one DD, 11. Both DH and I work full time, long hours in high pressure jobs and for many years life has been a real grind, struggling to meet the demands of our jobs, running the home, looking after DD, our families (large and with some "difficult" members on both sides) etc. We are both quite controlling people and have over the years become increasingly snipy with each other. Our sex life had dwindled to virtually nothing: he was still keen but I felt no desire (for him or indeed anyone else). Whenever we DTD my body hardly responded and I came to view sex as a chore.
Shortly before Christmas I chanced upon an email (which he had not yet read) which made it clear he had had a brief affair which he had just ended. The OW (26) was trying to persuade him to reconsider. I confronted him with it and he admitted all. I do not believe he has attempted to minimise or (once found out) to lie - he has answered all my questions and I have seen all the emails between them. He is full of remorse and wracked with guilt. He said he was lonely and unhappy, but totally accepts that he behaved despicably and hasn't suggested that any blame lies with me. I believe him when he says that this is the first time he has been unfaithful apart from a drunken snog at a party years ago (which I have only found out about just now).
I think that the affair was a stupid lapse on his part and that it is not a good enough reason to end our marriage. I have therefore decided to forgive him and carry on but he is under no illusions that he will get a second chance. Thinking about it all is still incredibly painful, but I expect that will recede as time passes.
We have spent a lot of time discussing our emotions and strangely I feel closer to him than I have for years.
What has been totally unexpected is that I seem to have rediscovered my mojo and sex is as exciting and as good as in the early days of our relationship. I have told him that he is not to read too much into my newfound horniness and that it's probably just hysterical bonding. I don't know whether this is simply a side-effect of all the emotional fallout or whether its something I can hope will continue. Has anyone else experienced this? It seems totally extraordinary that an affair can have had the result of bringing us so much closer emotionally and physically. Can someone please explain??
