In need of advice🤗 also posted in wrong category !

So I found out my other half for 5 months use too hang out with his mates and get a lot younger girls over too get more drink is what he says but he also used them for sex i freaked out I don't know what to do and I said I could get past it but I said it too soon I think. I find it rather disturbing and it's always on my mind.

Honest what would you do?

I have children involved as I have 2 both boys and they have got use too him etc I'm really stuck!

Please no negative

Thanks girls 💁🏼

Also this was just before he met me and he's over 20 and girls would be young enough too be vulnerable.
