How to tell if an ex boyfriend is jealous about a new boyfriend?
I'm curious as to why my ex reacts the way he does when he finds out I'm dating someone new. My boyfriend (at the time now ex bf) and I were really happy. My ex any time his name was mentioned he'd either run away or go from smiling to a complete poker face. We broke up to years ago. Is he just upset I'm happy or is he jealous?
