Do I ruin my chances to get my ex back by screwing his friend?

Couple days ago I hanged out with my ex-boyfriend’s friend and I got drunk and he sorta raped me. I told him not to tell anybody and did a pinky promise.
the next day. He blocked me and told everybody in town that he screwed me and how easy was it.
It hurt my feelings a bit but I’m worried that, what my ex-boyfriend will think about it. Would it ruin my chances for him ever coming back to me or he might feel jealous or I don't know
