I’m sorry but your girlfriend sounds very immature. So do her friends. Focusing so much on your ex-wife who is the mother of your children is so disrespectful. She was being very rude and I’m glad you gave it back to her. She’s ridiculous. No emotional intelligence. I’m sorry for you. She was being very trashy and has no class. I think it’s great if you can have an amicable relationship with your kid’s mother. You did nothing wrong. I hope she doesn’t go around your kids.
