Okay, I'm not a newbie to relationships or this forum but things have been going *weird* for me here. The guy isn't my boyfriend and I don't hope on getting a boyfriend at this time of my life coz I wanna be single, but I want to go out and have fun. So I accepted this guy from my class' invite. We go out alone sometimes or hang out in school, but sometimes we go out with fellow classmates. He's nowhere as good as my ex, who I still contact, but somehow, there is still some warmth between us. But recently, he has gone silent after I wasn't being honest about taking his things. I take his things for fun but didn't know he had some serious work in there to complete, I completely freaked out when he said he would go to my place to pick it up so I started avoiding his calls. I didn't know things would get so serious as now. He persists to say he still likes me and misses me but I feel that the romance, the flames are all gone. How could this be?

Just being curious, apparently the guy isn't important in my life but I would like to understand from the perspective of a guy..

Some of my guesses:
-he needs personal space
-he is busy
-he needs to reconsider the r/s as it might grow into a bf-gf thing.
