Need advice for a WW who left Part 4

[dwh15]

Got a TM from sis-in-law tonight. It's pretty much as I figured. WW's sisters wanted to spend time with her but figured she wasn't going to start communicating with them again until they agreed to meet OM. She said the meeting went fine but awkward. Said OM seemed nice overall, which I agreed. He does SEEM like a nice guy, except for the fact he's bedding a married woman and breaking up a family with 4 kids.

It made me feel better to hear that sis-in-law said they still consider me family and didn't plan on really taking in OM, other than the absolute min necessary so that they can spend time with WW. Prob be pleasant at holidays, etc. Now I'm not ignorant, and I realize that after my D is final, and the longer OM stays in the picture, he's likely to eventually be at least begrudgingly accepted by the family. And I don't expect them to shut him out forever, if the relationship ever reaches a point where it becomes long-term, which still seems highly unlikely. But I do believe that I'll always be accepted as well, and that's about as good an outcome as I can hope for.
