AIBU to feel hurt hearing my ex talk to someone else?

[ThisCoralExpert]

My amd STBXH are going through a divorce. I’m leaving because he has cheated on me in past - multiple times. We have agreed our divorce and will be thinking of selling the house etc soon. But.. it’s still hard to hear him talking to someone in the living room. Been together 15 years now kids together. I know I asked for the divorce but AIBU for feeling this way ):

You were all right. After I ignored him. He asked if I didn’t care that he was talking to someone. I said it’s not my problem. Then next it was the begging for forgiveness and the I’m sorry speech 🙄
