Because maybe he's insecure and needs to make sure that you dont still have feelings for your ex
He regrets it
So he could know about there boyfriend
You should be confronting your ex and telling him you do not like his girlfriend asking your children about your new boyfriend and if it keeps up he will only be able to see his children at your home or without his ex girlfriend.
Your ex boyfriend must felt guilty about the breakup and it is how you handle being around him that may give off vibes that you are mad at him.
he is either still in love with you or he wants to know the different bewtween him and the new boyfriend and see who u liked better
dump him he obviously prefers his ex to you!
Pray and move on...
get over it and move on
Yes, and you demand that they stop!
just tell your new boyfriend that you still have feelings for your ex and tell your ex that you have a new boyfriend if they really care about you they will understand
i wont disturb him
asking him might work better than asking the internet
get a new boyfriend
either he wants something to remember her by or he still got feeling for her
