Hi everyone :) Happy new year!
Speaking of new year celebrations, last night my group of friends and I spent the new year eve at my closest friend's (and soon to be roommate) house.
Very late into the night we were all settling down to sleep at his place, and him and I ended up sharing his bed, as we've done many times before. And like all those times we cuddled and talked for ours, and at some point he kissed me. We kissed for hours but we didn't go any further.
It was unexpected but lit up something in me that I didn't know was there before. I had never considered anything more than friendship but I liked that sensation very much. And I still can't stop thinking about those kisses!
The thing is that I'm not sure what they meant, and I feel like we crossed a line in our friendship. Also we're about to move in together and I'm really worried this is going to mess things up. My mind is racingng with a million questions but I don't want to pressure him or create doubts/problems.
What do you think this means? How do I deal with this without screwing everything up?
