Strong EA after 2 years of marriage. Need advice.

[Complex]

In the five days before ILYBINILWY, we hosted a divorced friend of my W (now single and sleeping around a lot). They went out for fun activities, coffee and drinks while I worked and took care of the kids. Guess what they talked about during that time? Let's see: my W came back some of those days saying "My friend thinks you're not good enough for me" and "My friend said her D was a liberation and how she found her true self". Three days later, she was leaving me "to find her true self". See: she was talking about us with her and and when she sat down with me, it was to announce her decision. Like you.

Very strong similarities Mozza. Actually my W best friend is divorced.
I heard the sentence "some people are not meant for each other, blabla" many times. That's what her D friend told her about her Ex H. Later I found out that he was abusing her. Which I didn't but if I draw a picture everything makes sense.
D friend also knows everything and supports her obviously. It's ridiculous how outsiders influence other people contra their marriage. It's non of their business. But WAWs obviously search for confirmation of their new feelings.
I told me wife I don't tolerate/accept that she put other people before our marriage and me. I once read that you should actually put your marriage before everything, even your kids. Another healthy boundary. If people put other things or people before their own marriage they came off the path already.
