Weird behavior that i don't know whether it is "i like you or not"
Yet another love question. Prepare for a long text. I have met this boy in spring, we work together in our free time as volunteers. We are the same age, have the same backgrounds more or less... He started just staring at me, and being near me at events, he teases me etc. I have told him a couple of months ago that i find him sweet, and that he is cute when he makes me smile when I am sad, without having a relationship in mind. He just said: "oh, well, I find you amazing, but I have just gotten out of a relationship and ... are you coming back?". The relationship thing is false, I kind of asked around.
I live in a different country, like our.. birth country?, and I have returned to this country, where we met, 2 times now. I have waited months to see him, I have spent so much money on everything just to get there and be next to him, support him etc.
He just stares at me and has the same behavior. Oh, wait, he recently enjoys just staying in a room with me in complete silence.
He asks me constantly when am I moving for good, but I admit, I was afraid to tell him that some aspects regarding my education refrain me for staying there this semester. When I finally told him this, his reaction was unexpected: he said "oh...dear lord" as if his whole world crumbled, and stayed with me 1 hour in a combination of alternatives for me to stay there and silence. He asked me where were I in the past 2 days, why haven't I appeared anyways, and I explained that there was no need for me to go to the office.
Last night I went to a party, he showed up as well. Whenever I took a beak from talking, and stood by myself, he stared at me. I admit, I wasn't feeling that well, because of being tired and a bit hungry. When we parted ways, he insisted me on giving a call on Monday, because I am leaving on Tuesday, probably go to our workplace or something... I just left alone, not even looking at him.
What the hell should I do about it? I work with this guy, and I really don't want him to think that I am a desperate girl or anything. I have strong feelings for him, but I don't want to be a bother, and I don't want to be perceived as just another silly girl... Sometimes I just want to scream at him, just tell him already, get shit done, but I don't want things to get awkward. I don't want him to avoid me every time or give me a judging look... It is just consuming me every day, I need some advice from you guys. Yeah, I am a girl in my early 20's who hardly knows anything about feelings etc, but help me to get a hold of this...
