<human>: So i am Graduating Highschool in one month, and want to invite some people to celebrate my graduation. 

Ive seen different peoples party invites and theres people with a couple friends, 30+ 45 even 50 people or only like 4-5 with friends of friends.

My question is, what are the guidelines for inviting people to a party?

I haven't really hung out with anyone this year and i have issues making friends, the closest thing i got is some girls that like me flirting, and a friend who goes to my gym every day but ive seen him once.

I feel like I talk to people and they enjoy talking with me, but i haven't specifically spent time with them.

Notably I have several girls that like me, but im not sure i want to invite them to a party because my goal isn't to get laid, they aren't attractive but they are nice girls.

Can you condense the text into a few key points?
<bot>: Lacking friends, Have made steps forward don't know what the guidelines are, have non-mutual attraction with some friends, Don't want to get laid but at the same time I haven't hung out with anyone really.
