You are handling yourself really well. And Valentine’s Day sounded like such a good time. You dear girl are doing very good by your kids.
W is flipping and flopping back and forth. She says one thing and then another. You are right, never quite sure who is going to show up. Even her actions seem to flip flop. I suspect OW is talking to her, feeding her agitation. You just keep taking the high road, and remain calm - and do it for you (and trio). W notices how you are and how OW is.
She is a hurting person, and you are being a very good role model and guiding light for her. She probably doesn’t even realize it, within her storm and battering waves, there is something there, something calm and comforting, a lighthouse in the distance.
Keep the faith.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
