I never had so much friends and now having some but do you invite your guy friends at your flat? I wouldn't like much guys at my flat, only girls... What do you think?

And I realized I shouldn't be close with anyone because you can have only so much friends and you should choose them wisely? I met a few guys who are in need of my help like asking tactics for girls and they are a bit broke, I feel like I shouldn't be close with them ( I became close since I don't have much social experience ) I wouldn't want them at my flat as they are at dorm and I'm planning to rent a flat near school. I feel like I should have friends above me both financially and experience wise to keep learn and grow, I feel like I'm not in a place to be a baby caretaker at 28.
