Bf and second thoughts..

I've been with my bf since October 2014 and we've been doing great. In April, his parents invited to their lake house for the summer and I agreed. Well we've never spent the night with each other, but since we got here, we've been having sex. It was great, no lie. But I'm noticing things I didn't before...I don't like the way he chews his food, or the way he gulps when he drinks something. I hate the way he grunts when he's getting comfortable in bed. He snores...idk why I'm feeling like this and this was supposed to be the summer of my life. He started talking about "when we get our own place..." And I just felt like running away!! What's happening 😩
