Thats the problem, he isnt dumping her. He would have already done so, now he is showing his insecurity by trying to keep her with childish threats "if you do that then ill do it too!".Danger said:I don't see how the boundary crew makes it complicated.
It's very simple. No hanging with ex's. If she knows you do not like it, but she does it anyways.....just dump her.
Presumably in the four months they were dating he already knew about this guy. Why would he agree to be exclusive if he wasnt comfortable with what she is doing? If she was highly interested in him she would drop the other guy ON HER OWN because she knows it bothers him.
I agree with your approach in theory and maybe it works for you, but many men are using the boundaries to control and keep the girl out of desperation, not out of self-respect. World of difference there..
