PLEASE don’t allow this ‘man’ anywhere near your children! His, his wife and his children’s feelings are not your responsibility, your children’s safety is!
If he is on the Sex Offenders Register he will most likely have restrictions on contact with children, please check with your local police, and the school as pps have said. This is really important, please don’t assume someone else will do it.
I am gobsmacked the amount of people on here who would willingly and KNOWINGLY let their child be in the presence of a CONVICTED child sex offender. I do not care on the situation or location, it happens. Regardless of other adults being present, and whether he would have actual contact with my children, I don’t care, just the thought of him being around and thinking about all of those children is sickening, and anyone who is not angered by a child sex offender at a children’s party needs to give their head a wobble.
Before anyone says, I went through years of abuse as a child, and this involved grooming, so yes I know from experience how under the radar they fly.
Even without the children, I wouldn’t want to be near that ‘man’.. and to be honest, he wouldn’t want to be in a room with me either so..
OP, the best way I can suggest to explain the situation to your children is to tell them it’s your job to keep them safe, and unfortunately that ‘man’ is not a safe person for them to be around. If the mum has a problem with it then she also needs to rethink her decisions.
It’s a terrible situation but it’s got to be done, you would never forgive yourself, believe me. Best of luck lovely.
