I've namechanged for this because I don't want it linked to my usual posting name. Am a MN regular.
Been married 29 years, in our early 50s with 3 DC in their 20s who all still live at home (but that's another story!). I have severe health problems which limit my mobility and I am also short of breath even at rest sometimes. These have been worsening for the last 10 years, and I have been in Intensive Care twice in the last 4 years. My ability to have sex is nil, and I am not interested anyway, and this has been the case for years.
My DH works hard, he is self employed which means he has been there for me whenever I have been more unwell, takes me to appointments, does a lot around the house, and listens to my fears about my health. He had an affair 4 years ago, which I discovered through texts on his phone, but I forgave him because I need him, basically.
About 8 months ago we had a very brief talk, I basically asked why he stayed with me, he said he is committed to his wedding vows, and I said I would understand if he sought sex elsewhere as long as it did not affect either me or our children. He didn't really say anything then and it's not come up since.
About 4 months ago I realised he was shaving his private 'bits' - I have not let on I've noticed. He's always worked long hours, and goes running and plays football, but he's not been out longer than usual, or been different at home, until this last week.
He seems totally unlike his normal self - it's hard to explain - after being stuck in such a rut he seems happy. He left his computer logged in last night - and I looked on his e-mail - he has met someone 20 years younger than him, and I think he's not just having sex with her but falling in love with her.
I want to change my mind - he was home late from work a couple of times in the last week and her words about the way they spent those early evenings are imprinted on my mind now. I don't mind the sex - but I just don't want this to be happening. What do I do? I can't stop thinking about this and I wonder if it's all my fault.
