I got my H to go on Prozac...this was after getting ED / Thyroid Removal / bouts of anger coupled with lack of motivation...then depression. I led him to Prozac. I know now, from reading so many links, thanks to this forum...I compounded it all and made it worse.
When he was leaving, he said "I feel dead inside" He did not love me, the dogs, his friends, his house or his life. Later when asked by a close friend, if OW was his new love...he said no...very matter of factly. So though he told her he loves her...I doubt he really means it.
