What do you do if the guy that broke your heart still flirts with you?

He is playing with your mind...bc he probably has no one else to flirt with...so he may be using you as someone to play around with...up until someone else comes up. Don't fall for how he acts. If he really wanted to be with you, he woulda kept ya and never dumped you. What he is doing is full of BS. Trust me...my ex was like this. Still is today...unless he has another crush to flirt with. Stupid.
