how do you make someone want to spend time with you?

It’s not really about you vs his friends. If you want to spend time with him and he has other plans it’s not going to happen and it shouldn’t have to, you should plan ahead a little and make plans with him when he doesn’t already have any. Maybe when he isn’t busy talk to him about that and see what will work so you can spend more time together without having to sacrifice either of your friendships in the process

You can't. He is what he is.. If you see this trend now perhaps he isn't as serious as you in this relationship....

some people just need one person to be happy, and some people need lots of people to be happy.

sounds like he does want to spend time with you (you do live together, after all), but he needs to spend time with friends as well.

If i can be blunt, you need to learn to be okay with that. Relationships are about give and take.

make yourself less available

You need a serious answer but I’m not a very serious person. Or am I 🤔? Fuck I don’t know. Just maybe find some friends or something

Do you live with him?

If he does that now, it's over and the two of you just haven't realized it yet.

Hmmmmm are you menstruating by chance

I sympathize.
