I have similar feelings. I found out some stuff about a year ago. I have gone through every emotion. We are trying to work through it but it is very difficult. I don't hate him, but am very angry at what he did. I have been very detached as I try to process what is truth and what is lies. At the same time, if we are trying to reconcile, I'm trying to get along with him. It all feels very flat. We don't joke and play like we used to, sometimes we still have sexual contact, but there is a lack of intimacy and love.
We mostly avoid talking about it, but I am at a point where there are some things i need to tell him about what this did to our marriage. There are also a couple of relationships that he had with other women that he has continually insisted were not sexual, but I am still unsure. Of the two infidelities I do know of, one he said was just kissing, the other he was trying to come on to a co-worker, told her repeated times he was attracted to her and wanted to have sex with her. She denied his advances and sued him for harassment.
Where we are is not healthy. We need to renew our love for each other or just separate. Of course, having a 10 and 12 year old doesn't make it easy for me to just leave, and we have a very complicated work and home life. I do love him, but this whole thing has put quite the strain on us.
