Party life.

I have only been with my boyfriend for about 9 months. After 2 months of dating he had moved into my parents house. We had planned on him moving out when I turned 18 and we were going to get a place together.  Recently my parents and boyfriend got on each others bad sides due to him losing his job. So he moved into my friends house and my friends are huge party people. He has been with me everyday for the past 6 months. And now he wants to still be together but not have the title of dating so he can go out and party not feeling guilty for not being with me. He also may or may not have gotten me pregnant. It's too early to tell and it's not something I want to bring up to him until I'm 100% sure.. The point is, I'm in love with this guy but I have felt like he is choosing partying over me. We still hang out, but we are both usually sleeping when we do, and this has been stressing me out, and I don't know what to do about the situation, any advice?
