Karen,
I suspect this woman's outrageous behavior is the result of her being insecure about her relationship with your husband. Right now, you are as much of a threat to her as she was to you. The relationship she has with your husband is based on lies and deception (on both their parts) and has...and will ALWAYS have...an unstable foundation.
Knowing what they have done, the only way she can possibly jockey for your position within the family and social circles you and your husband shared together as a married couple, is to run a campaign against you. Otherwise, she would have to deal with a lot of ridicule and scorn which would also threaten this new relationship. Believe me, the friends and family that knew you the best will see right through her bizarre little routine and eventually it will work against her.
She’s scared out of her mind. GOOD! At least you can find some restitution in that. Keep you chin up and make sure you get all you can from this divorce. Stand strong against all the insults and accusations she throws at you. The less you appear bothered by them, the worse she will look. And since it appears that your husband may be a habitual adulterer, my bet is that this relationship will run its course and be over once all the drama fizzles out and they become settled in their routines and “bored” with each other. And that’s when all the bad karma will come back around to bite them on the …..
Hopefully, by then, you will have worked through all the anger and pain and will have already begun a new, HAPPIER life on your own. Once you get through the difficult divorce process and have had time to be on your own
without all the added worries and stress caused by your marriage, you will realize just how LUCKY you are to be free of him. And being “Happy” is often the
best revenge.
