<human>: Me: f,20     SO: m,21     relationship: 4 years. Roommates: all male, ages 21-23

I've been with my SO for 4 years now and, this fall, he's moving in with 5 other guys. I know and get along well with all of them and consider them to be my friends. However, my boyfriend wants me to be over there all the time. They all seem to be okay with the idea, but it makes me very uncomfortable as I will not be paying any rent on the place and the 6 of them are. 

How should I deal with this? I don't really want to offer to pay rent on the place as I have a apartment of my own that I'm already paying for and can't afford two places, but I still feel like I'm free loading.

Details about the place: they have a flat rate every month with water and electricity included so anything I use doesn't up their bills, same goes with internet. My SO has his own room so I will not be encroaching on another person's space. Advice?

Provide a brief overview of the text.
