Would this be ok with you?

Hiya, everyone, long post here. Also just for some info we've been together for 10 years.

So my question here is, would you let your partner (heterosexual) go wild camping with the opposite sex?

Right, ladies and gents, I need some advice here because if I fetch it up, he just goes on one and doesn't really let me speak and makes me out to be the bad guy.

So a little background we have 4 kids he's been going on hikes for roughly 4 years, and he started getting to know different people and goes with a group now. I don't know them, never met them. I don't go hiking as I'm at home with the little ones (they can't walk as far as he does as I mentioned about me going with the kids as I love that sort of stuff too) he now does nights out every now and again with some people from the group and wild camped with 2 women a bloke and himself (so 2 men and 2 single women I'm not sure if the other bloke is with anyone. ) recently, he went wild camping with 5 men, including himself and 7 women, he follows them all on insta and they all follow him too and one of the women he follows on insta he likes her bikini pics I think this is disrespectful but I'm wanting your thoughts.

He also goes to pubs and stuff with them,they also like to go in the lakes in their bikinis while they're wild camping too when it's nice and they also like to hike in their thong bikinis too.

So my question is, would you be ok with this or not?

My head is all over the place at the moment. There's alot more too but it would be too much to write.
