I went through the same hing with my ex. I suspected he was cheating for a long time and of course he always said no that he would never do that. Then one day out of the blue he said he wanted a divorce. He told me if I got back on meds and changed some things we could work it out. He said he needed to separate while I did these things. I did everything he asked and then found out from a friend he had moved in with his girlfriend he had been cheating on me with when we separated.

I'm so sorry this is happening. I know how it feels. Hugs.
