I never dealt with the Affair Partner because it would lead to a very late Abortion...
Usually the AP are rats, your partner chooses them because they are morally bankrupt enough to roll in the mud with them and your partner feels they are low value so they feel like having the upper hand in this relationship (usually cheaters suffer from low self worth).
So that she was being shitty with you is unsuprising.
Also consider, AP and Cheaters are from the same fabric. So the AP is low self worth, if she can get a one up with you that would make her low self worth as a woman get an ego boost.
About women AP, I saw the behavior you described few times already, seems women AP actually kind of seek validation in confronting the betrayed wife for ego boost, that doesn't seem as likely with male AP because ... late stage abortion risks.
Consider this: she is the dump of your worthless husband to get his ego boos feeling superior to a partner.
She knows that too.
That's why she tries to hurt you, so she can feel like a woman and not a rat (by being a sordid worm, but hey... not a rat at least... win win I guess?).
That said, is not just a pep talk to make feel you better, is the reality.
You are not in competition with her, a low value woman can never match a woman.
The moron is your husband because he thinks very low of himself and does not realize the luck he had in meeting you.
Right now, to hell with the AP, the only useful stuff you get is that what she told you to hurt you and feel better about herself, will also unmask all the bullshit lies your husband tells you.
It gives you clarity, is a weapon you can use, to protect yourself and see your husband for who he truly is.
Right now you must heal your wounds sister. Put yourself first, do not shut down your emotions, you can share here and be heard.
If you need advice you will get plenty of solid ones here as well.
It's not okay, but you are stronger than what you feel now. I am with you.
