I hesitated to post this story before because I wasn't sure but now I am, so I will.
In the early days my boss asked me if everything was okay with me, it must have been pretty obvious it wasn't. I told her some of what was going on and she confided in me that she had been through the same thing. I wasn't sure at the time, her H never left home and I didn't really have enough detail. However having talked to her again today I now have no doubt. She had 5 hellish years, for the first 2 he had absolutely no physical contact with what so ever, blamed her for everything etc etc. He has huge foo and self esteem issues.
Eventually she could take no more and said if he didn't do something she was leaving. He was not in a financial position to move out himself. He then agreed to see the doctor and spent the next 3 years on medication and in therapy, (all the while saying he didn't need it, he was only doing it for her). Eventual he began to reconnect, at first with their D and then with her.
The only thing I don't know is if there was an OW. She was very quick to ask me if that was the case with me, so I am guessing yes but she didn't tell me so I didn't ask.
She also said she went through her own transition following the death of her mother just prior to her H's crisis.
Anyway the good news is they are now very happily reconciled, she feels she "has her H back", although it sounds like he is still working through some stuff.
She is a different person to when I first knew her, so much more relaxed and happy. It quite cheered me up, except for the 5 years!
