Just by you being a bigger person show that your a threat wen she see yu doing good then thats gone give her even more reasons to hate nobody like to see yu do good
maybe she's insecure.. i'm not assuming anything but.. do they have a children of their own?
its wrong of her to be messing with the children, she has insecurity issues. if she thinks youre a threat, well she thinks everyone is, im sure you didnt spend all that money divorcing just to get back together. she sounds like she has no love or self confidence. he may not be the one for her, esp messing w your children, thats a big red flag.
if there's kids there has to be some involvement......but make it as limited as possible
Does it matter? Do you have a kid with him?
Thats messed up. Sorry to hear.
