My boyfriend (23) is very outgoing and has a lot more friends than me (23). He recently went to a houseparty with them for the first time in the year we’ve been together. I’ve never been to a party because I’m not into that, even when I was at university, so this is all new to me. Ive also only previously been in a relationship with a person who didn’t go to parties so this has never been a worry to me. I may be naive as all I know about parties are drinking, drugs and sex, as portrayed in movies. I’m not worried about him cheating as I trust him but I worry about what his friends are doing and whether they are influencing him (they do drugs and go to strip clubs but he is very much against that).When he went to the party he did message me and update me about what was happening which did reassure me. I would never stop him going to a party but I just can’t help but feel uncomfortable about the whole situation as it’s new to me. I forced myself to be okay with it when deep down it makes me anxious. They also all stayed overnight. He is generally a good boyfriend and he rarely drinks/goes to parties anyway so he’s not a party animal. But I find him very contrasting to his friends which makes me wonder why he even hangs around with them. He tells me sometimes they make him feel left out and he can’t always be himself around them which makes me worry he may try to ‘fit in’ with them.Does anyone have advice? I don’t really want to bring it up to him because I worry it will cause an argument and I will come across as being insecure.
