Then you made the right decision.
im sure the same thing wud happen to me if i did that
It depends why you broke up with him, if you just went out with him a week or two ago, then why would he care, just another girl on his list,, but if there was special, then he might just be putting on a little tough guy act
So, if you broke up with him, why do you care?
either he cares and is afraid to admit it or he just doesn't care...either way give him his space and find your own happiness, if it meant to be it will <3
Maybe it's because you called him "my guy"
Sounds like a good move, if he shows no sign of caring.
