I think my wife is in MLC and it seems hopeless

[SBJ]

Vapo...as for the EA, she never admitted anything, nor did he, but this guy was someone that we welcomed into our home as a family friend. He didn't have too many friends, so we opened our home in a Christian way to him. I won't go too much into his story, but he is an ex of sorts. He is ex-this and ex-that, and seems to be a very manipulative person. He and I worked out together and talked fairly often, but obviously not as much as he spoke with my wife. In hindsight, I'm the one that left the door to the hen house open, but that is neither here nor there right now. Over a 3.5 month time span they got to be very close (phone calls/texts/lunches/coffee). I knew that they had had lunch and coffee several times, but I was unaware of the time that spent communicating until I pulled phone records later. It was enormously ridiculous. Again, they both deny anything, but then I look at the...only believe 1/2 of what they say statement.

I think that she developed this infatuation factor and that is what flipped the switch. I've seen a word floated around alot called:
Limerence (also infatuated love) is a state of mind which results from a romantic attraction to another person and typically includes obsessive thoughts and fantasies and a desire to form or maintain a relationship with the object of love and have one's feelings reciprocated.

I'm no professional, but might fit???
