Weird situation after sex...iin?
Here's the deal. The guy is my co-worker and we both work in IT (we have a lot in common, plenty of common interest, job etc.) and we're both fairly young. We've known each other for a while and I totally adore him 'cause he is nice and handsome and all that stuff but recently I've got into this weird situation. We were hanging out at my place, we were flirting, he said he's in love with me and we had amazing sex (for the first time). I got sleepy (I always do after sex), so he kissed me on the cheek and asked if he could stay for the night. I said I wouldn't mind at all and there's a couch in the living room (which is comfortable) and he just said Ok and left my house. The next day he wouldn't even talk to me, making rude comments whenever I spoke (not even to him). All of our сo-workers had noticed that. I asked him in private why was he like that and he told me to take a guess. My question is what's going on? Is that because I wouldn't let him sleep in my bed, which is way too personal for me. None of my ex-boyfriends did and never had problems with that.
What do I do now? I really like him.
