I met this guy 3 weeks ago at my first lecture for one of my classes. We ended up sitting next to each other from then on and we would text frequently and sometimes played pool at our uni after class. For the first 2 weeks I felt nothing but friendship for him but when he texted me something and mentioned another girl in it - I felt strangely weird. I didn’t know what to think because I thought I only liked him as a friend but in that instance, I felt jealous of a girl he had merely mentioned. The next day we had class together again and I kept thinking about him and then came to the conclusion that I might like him as more than a friend. But then to my complete shock, after class he asked me out. In that moment, everything that I thought I felt for him vanished and I pretty much rejected him. Im just not understanding why all my feelings went away the moment I realised they were reciprocated??
