Guy's Behavior

What does it mean , He talks to me so nicely behaves like a damn gentle man Infront of me. Always interesting in asking me questions?

. Mostly his questions are about what I would prefer in a guy and how I behave in certain situations, he compliments me a lot too and tells me what I should do and what isn't good for me. He would just want to spend quality time with me. Even if I don't ask him or pay much attention and interest to the Convo he still continues doing it
He would try to teach me good things about living a life. He would try to confess him that how he is amazing like he would show me his veiny hands and stuffs like this and tell me about his good height and tell me that girls prefer tall guys. Most of the time he acts so dominating, his aura is kind of very scary as he is very mysterious. He never told me much about himself. But he wants to know everything about me even my deepest weekness and strength. He once gave me his ring and asked me if it's fits in my any finger. He asked me about my height too my weight too. this is all happened for 6 months. He kept giving me hints. I was struggling with a heartbreak I only told him as he made me trust him. Bcz of him I got out of the depression. I catched him staring at me all the time. Even when I look at him he would stare piercing through my soul. It's creepy to me. But I never asked him as he does make it obvious. I don't know why onece he asked me if anyone ever pulled my hairs I was like why would anyone and he smiled sheepily. Things were going like this. But then we had a break of 3 months. He didn't even text me once but he had told me he isn't a text person as text can create lots of misunderstandings. He is a very mysterious person. 3 months passed one day I even text him to check if he really likes me I played like I was anxious and wanted someone to talk to me I text him about it but he didn't pay much attention and didn't try to continue Convo. When I got back to my institute he stopped paying attention to me at all. I many times catch him staring at me but he dosn't aproch. He shows jelousy and anger when I m with male.
