XH is marrying OW after only 5 months of D!!

[luvless]

From OW:Has it not got through to you yet that i will be married to Paul and officially be the boys stepmother. Hope you enjoyed your visit this evening. (I assume this means the police)
You would know what trash was. never met anyone who is such a low class in my life.
You absue your kids mentally and when they are older the will resent you.
Did I tell you that we are very happy and that the boys love being with us. I too will be a Mrs S van Kooten - its kind of funny.
Sweet dreams .... Hope you dont have night terrors - if so borrow S8 light that we bought him. It works well.

I am not sure how to deal with this

This makes me mad as hell. What is wrong with people? How dare she interfere with YOUR children? It is not her place and she should look in the mirror and see the low life classLESS person she is. She is not a step mom she needs to step back!
