Turns out the "friend" was the OW. When he cam home this morning, he calmly told me that she asked him if he wanted to spend the night and he said yes. When I asked why, he said she makes him happy, and he is really confused and depressed right now..I confronted him by saying that I can't be in a marriage between three; he said he could not reply to that, cause he's not sure what is going on in his head or with him no more; he's simply unhappy..I told him he should then seek help, like he said he wanted too instead of using her as a pick me up..

He left again..I'm looking into filing for separation..
