K MIL is fully aware of what the issue is/was. MIL wanted to sit down with my wife a few weeks ago to talk about whatever it is that is bothering her. My wife postponed at the last minute saying all my MIL was going to do was "lecture" her. My wife complains that she never talks to her but when she tries my wife backs away.
A couple weeks after my wife had left we went to one session of marriage counseling. Our C said my wife had too many issues to deal with first before we could even think about MC. At the time my wife took it as a wake up call but dragged her feet to make an IC appt. She went to one session and that was it. This was about the time she started seeing her "friend". My guess is the high from infatuation made her feel as though she was better so she doesn't think she needs to go back.
The spewing she did a few weeks ago also was about her Mom and how no one in her family cares about her. I told her she should talk to her Mom about it and my wife said she didn't want to alienate her Mom any more than she already had.
