person A: I know I broke up with my ex_comma_ but I can't help but feel irritated when he talks about going on dates.
person B: That must be weird to talk to your ex still.
person A: We actually get along really well and are much better friends than a couple. I guess I still just get a littler territorial_comma_ i think he does too. 
person B: You must have feelings for him that are lingering.
