I'm in love with my best friend and don't know what to do.

My friend and I dated before but broke up because we just thought wr werent ready for a relationship. I still like her a lot and think I'm maybe even in love. We kinda stopped being friends fot a while because we both got really busy and just grew apart, but a few weeks ago I went to a camp type thing (it was at a university and we stayed there for a week and took classes and did competitions) and saw her. We became friends again and are closer than ever, but my feelings for her keep growing stronger. like even when i was dating my ex I thought about her. she's always on my mind and I want to tell her how I feel but i feel like its too soon. i dont know if she likes me, but at the camp thingie i was all by myself in my dorm so on the second night she came and stayed in my room on the other bed. but the third night she came and slept with me in my bed and idk if that means anything but idk. i really like her and dont know what to do. ;-;
