WAW w/Exit Affair or WW? - Don't Want Divorce (2)

[BL42]

S5 just told my mom that OM2 stays overnight at mommy's house and sleeps in her bed and they all eat breakfast together in the morning. He said mommy stays up late because of OM2. I'm spinning a bit right now: sad, angry, resigned. It just seems so inappropriate to introduce the kids to another person right now let alone essentially moving in and sleeping in her bed while the kids are there. I know from other sitches/posters on this board it happens and I can't control it, but it [censored]. Sure it was inevitable down the line, but so soon? Hate me for whatever reason, but be respectful of the kids. I've reached out to attorneys but it doesn't seem like there's anything to do.
