I recently moved to a new town and started graduate studies. One of the guys in my program started hitting on me the very first time we went out as a group and while I rejected him, he keep flirting and trying to get my attention in the following weeks. I was in a two year long distance relationship at the time but one night we started talking while tipsy and really connected and ended up having sex. I stayed over because he insisted and while I tried to leave as quickly as possible, he was very intense, cuddling me and kissing my face. We eventually hooked up again and it kept getting more intense, with us holding hands in public, going on dates and talking about things we wanted to do together. I usually stay over 5 nights a week though sometimes it is 4. Me and my exboyfriend broke up and from there it got even more serious, I already leave stuff at his place because he asked me to and we don't always have sex but cuddle all the time. Right before winter break, we vaguely talked about the fact that we have feelings and agreed on staying in contact while spending the holidays in out hometowns and so we have done. However, although he has hinted strongly that he considers us to be dating and that dating for him is exclusive, we haven't defined the relationship yet nor actually said direct things about how we feel about each other. We first hooked up on September 30 and I started staying over regularly after October 20. I don't know if I should asked him outright or just see where it goes. He has mentioned meeting my parents, and has compared himself to my ex boyfriends by saying that things that were problematic with them won't be with him. He also mentioned that he has shown my picture to his friends in his hometown and has at different times said we are a thing, that I'm his girl, and that I'm his lady.
