So we just found out our abuser might have a boyfriend 

We do not know this boyfriend, we have no contact and we are scared

Our abuser always said that he'd find a boyfriend the second he left us because he needed comfort or whatever but we know damn well that boyfriend isn't going to have any good relationship at all

He always says he'll be good but the fact that he doesn't acknowledge his wrongdoings in any substance speaks for itself

We're so scared, not just for the boyfriend but for the fact that this guy is genuinely going out and doing EVERYTHING we couldn't have because of him 

How do we even react to this, we shouldn't even know, we blocked him on everywhere and swore to never look at him again but we did

God, I wish we didn't

But wishing won't get us anywhere, but maybe advice will, so please give even a little bit of help
