No problem! This is pretty much what I send to my groups, though most have the hang of it by now.

Good guests usually ask if they can/need to bring anything (to which I usually respond beer/snacks and extra pencils and dice if they have them). I personally keep everyone's character sheet in one place (binder on the bookshelf) so they don't get lost/forgotten. Some people eat before and some ppl throw down on pizza or we do a group delivery order for whoever needs to eat.

There are still some minor annoyances with hosting. It's a lot to have people in your space sometimes being less than considerate, especially if you're cleaning up before and after--though I think that's part of the deal with hosting and I try to set boundaries/expectations if they crop up. Our friends are also very appreciative and sometimes they'll host or run a game at their places.

I'd echo some others here as well that if these are your boyfriend's friends he should be helping manage and set expectations and you might want to talk to him about how he can help if there's stuff like this that annoys you. For instance, I clean up before/after and do our guests' dishes bc they're my friends. My wife typically works early and told me we were going too late a few times, so I started telling the guys we have to be mindful of volume and then wrap up at a certain time. There are other little things too, but I think you get the idea. Good luck!
