Ahh this situation sucks.
A friends hubby has done this kinda stuff to me and has said and done some very inappropriate things. I didn't say anything to her as she had MAJOR trust issues so I just couldn't say anything. I kinda figured he was going through some sort of mid life crisis and would come to his senses.
Turns out he has recently cheated on her with a number of different (and questionable) girls and I think she is gonna take him back.
Some people just wanna stick their head in the sand and blame everyone else for their problems so in your case I would just give her a little time and space.
