Hello, sorry to read that you are feeling so bad right now. Your husband is cruel,nasty minded and vindictive to speak to you like he has done, but best to try and ignore his horrible words and actions if you can, as dwelling on them,will only make you feel much worse.
I am wondering why you would wish to contact any woman /women involved with your Husband. It would maybe just add to all the anger and upset that you are going through now.
If you have filed for a divorce, you are going to be upset, but busy sorting all this out now, so need to stay strong, and maybe get some support from your children or family if possible.
Despite how you feel now, if your Husband has a tendency to be nasty minded, and a cheat, then you will eventually be free of all this, although it doesn't feel like this right now.
