I have lurked for a long time and decided I needed to post as I have no one to talk things through in RL.
So I've been married 10 years and last year me and my DH started going through a really bad time. He wouldn't communicate at all, he was stressed out with work, constantly glued to his phone and xbox. I was stressed out with my DC behaviour. I felt isolated and seemed to be doing everything. We also had FIL problems and his grandma's long term husband died (so his Grandad). Things went from bad to worse from September onwards, I told my DH I wanted to divorce. He had no where to go so we remained in the same house. Didnt take me seriously. About a month after this time I started talking to one of his friends. I had met this person once (group meeting) We started talking on a daily basis. He admited when he had met me he thought I was attractive and I said the same. We started talking more and I started hiding it. I knew at this point I had crossed the line but part of me wasn't bothered. I felt shit but he cheered me up. My DH wasnt engaging at all with me so I thought it was ok. Things then started to get more intense. We shared pictures, messages and video called often but my mood wasnt improving and I contemplated suicide, my family and life were a mess.
Then I went to the GP, started ADs and therapy (12 sessions in total) My DH also started ADs and CBT (online) Things between us got better. We started talking and sorting out the massive things in our life. I told his friend that I couldn't continue as we had been and he got upset but said he understood. Hoped it worked out between me and my DH (I dont think he meant it by how his messages were getting).
I havent spoken to him since before xmas last year but he is still in regular contact with my DH and their group of friends.
I'm really torn. I did an awful thing. I was still married. I shouldnt have spoken to the other man (he was also in a relationship) and I deeply regret it.
Things are finally getting better between me and DH, mentally we are both in a good place.
They talk online (gaming) with a load of others.
Should I tell my DH what went on? There is no chance of me doing anythinf remotely similar in future. I feel ill just thinking about it all.
