Hi OP. I am going through similar.
I’ve been unhappy in my marriage for about a year. My DH isn’t abusive or a bad person, we just have no connection any more. We got together and married young, had children very fast and now I feel as if we have outgrown each other.
I’ve been having what I suppose is an EA with a colleague, nothing physical but we text and talk a lot and I have confided in him that I would like to end my marriage. He tells me he does have feelings for me, but I should not make any decisions based on him as it would never work for lots of reasons. He has encouraged me to be frank with my husband about how unhappy I am so we can either fix things or I can leave.
I actually told my husband about my EA. He was very hurt but said he could understand how his behaviour had driven me to speak to someone else who was willing to listen and empathise with me.
We had a conversation last night where I said I didn’t feel the same way anymore and thought I would be better off alone. He told me that if I left he would kill himself. So I feel I am completely trapped.
I’m also dealing with my feelings for OM, which are very strong. I feel as if I am going through a break up which no one else knows about. When I think about not having him in my life I cry, but I know he is right. There are so many reasons why we would not work.
I feel as if my husband deserves to be with someone who can give him the love and affection he deserves, but I can’t see a way out at all.
