I would tell my partner that this person is the past. I am with you now and not comfortable at all with any ongoing communication. If your partner has any respect for you they will sever all communication.
you either move on or stay with him or just go about your business focusing on you because apparently he have feelings for this ex to still be talking to her.
It is obvious you are still in love with your ex boyfriend and hoping to get back together with him or it is wishful thinking that he will contact you and therefore he is on your mind a great deal so it is normal to dream that your ex boyfriend is trying to contact you. If he does not have a girlfriend then out of curiosity contact him and see if he will meet you somewhere. Take the risk.
dump him he obviously prefers his ex to you!
contact him
Pray and move on...
get over it and move on
Yes, and you demand that they stop!
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.
Ignore him. Works well.
either he wants something to remember her by or he still got feeling for her
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.
We would say that maintaining a friendship or maintaining contact with an ex is usually a good thing. It often means that there is no hostility between them. If he has asked you to move in with him, then he obviously likes you and does not harbour feelings for his ex otherwise he would have asked her to move in. Follow the example set by your boyfriend and his ex and TALK to him. Good Luck! - TrustworthyOnes
Your boyfriend should be the guide to show you how to "deal" with it. You should be polite and courteous. If there are jealous feelings or you feel you cannot deal with it , you know it is time to move on.
