my boyfriends ex

Tianna

so this happened yesterday night just after I got home from spending the evening with him and he texted me that his ex girlfriend texted him and said hi but he didn't respond and I got mad at him and told him to block her then he did but I got mad because of the whole situation because I have all my exes blocked so they can't reach me or anything but did I over react or do something that I shouldn't have because wow i still feel mad about it because he brings up exes more then me. is there anything I should think or do that could help the way I think or perceive the situation?? I think i get jealous easily.
