Depends what his conditions say/are.Did he do anything wrong tho we were talking? he never mentioned kids at all. it’s not like the offence was just a one off tho he had sex with 3 different minors he has a SHPO and will be on the register for life. I think all this has just hit me how bad it could have been.
I would personally report because imo as soon as he knew you had children he should of ended that conversation . Even if it’s just making them aware.
