Search Results: Why does he act like that

A guy I work with that I have known for years and I have always had a playful relationship. We banter, joke and pick on each other during breaks. He and I started a casual fling with the understanding it wouldn't be a serious thing and that it had to end if feelings were attached. So, we go on this way for months, never hanging out outside of work except for hook ups. Feelings grow. He acts jealous when I talk to other guys, he goes out of his way to make me jealous. He lights up when I walk into a room, this warm, glowing smile on his face. He goes out of his way to look out for me, and a couple of times he says love you to me as we get off the phone, quietly like he wants to make sure I cannot hear. He goes through days where he burns super hot and cold, nervous and jittery around me. When I first say it back finally, he seems happy or giddy about it. I say it a few times, only as we get off the phone. The last time, he seems nervous, and does something to intentionally make me jealous afterwards. I get up the courage to ask him if it bothers him that I told him I love him. He asks me why, and when I won't tell him right away he says I shouldn't and flips it on me, saying what we have was supposed to be casual and why did I allow myself to catch feelings? He keeps asking why I love him but then apologizes and says I don't owe him an explanation. I finally ask him if he feels the same and he says no, that he's sorry he led me to believe he did.

I have a college crush. He is very outgoing and extroverted. He is the CR. I initiated convo with him regarding an assignment submission. And we talk a lot over text. I ask him to help me with studies, to teach me some sums and he always does that. We have also called each other and solved sums together. He is a genuinely helpful guy. He talks with every girl and makes fun of them. He is a bit flirty. He will talk to my friends in front of me but won't talk to me. He never makes fun of me and gets shy and nervous whenever I try to talk. I'm an introvert myself.

As exams are coming up he said we can't solve sums on call if I have any problem he will teach me in college. So the other day he came and asked me so bluntly that if I need any help. I said yes and he came, sat beside me and was teaching me that. And it was awkward, he was kinda reserved. Then his friends started teasing him saying 'what's going on between you two' he was just smiling.

I also punch him some times playfully and he just smiles.

He speaks with everyone nicely but with me he acts different. He teases every girl but not me.

All of a sudden whenever we bump into each other he has started smiling and says hi. He also blushes. Today also he looked at me and smiled. He came towards me as if he was trying to playfully punch me then he gave a fist bump 😂

I can't understand if he is an outgoing guy why doesn't he talk to me in college like he does with others? Why is he so serious with me? Why does he talk to formally? Does he not like me? But when I call him he talks very nicely.
