Girl, you are doing the right thing and I can only imagine how crazy difficult it must be. Take some comfort though in knowing that all that OWW "won" is a crappy husband!
My kids were college age when my ex left and I am forever grateful that the girl he married was not One of his affair partners, but someone that he met almost a year later. Still it's difficult because she's his Asian "dream girl" and almost twenty years younger. She wasn't responsible for the end of the marriage, but the IDEA of someone like her was. I'm grateful that she treats my kids ok but honestly I would have trouble having to spend time with her the way you do with OWW, and she wasn't even around when ex left! I admire your fortitude and yes , doing the right thing is HARD sometimes but that's what we momma bears do for our kids.
My sister - same one I mentioned above - had to make nice with the OW that her first husband married, because her oldest daughter would visit them and OW went on to have two boys who are my niece's half brothers. When my sister's ex cheated on that wife too, the OW wife actually apologized to my sister.
Think how often your Ex's OWW must think about the possibility of him cheating on her. If you marry someone in circumstances like theirs, it must never be far from her mind.
