Falling for my roommate...

I moved in with my roommate a month ago after a bad situation with my cousin. This guy is at least 10 years older than me and he's my coworker. We met each other at work in February or March and he has always had a thing for me. Well I kept my distance for a while, then became friends with him. And when shit went awry with my cousin, he offered to let me move in rent free, with nothing asked of me really. Finally a month ago I move in with him and we slowly gravitate towards each other. Now I am starting to fall for him, but we went from just hugs to kisses to sexual activities in the course of two weeks. I'm just nervous that we are going too fast or something, but he cares so much for me, which is something I've never had in any relationship. He makes me happy, and I am the stars in his sky. I just had to get this off of my chest and see what you guys thought :)
