What do you think of our relationship?

This guy and I have met a couple weeks ago and we've talked to each other everyday. He replies instantly to my messages and I do to him too. Recently my friends asked me about him because they could see the 'chemistry' between us and they could tell we obviously like each other. We often link arms, hold hands and he kisses me on the forehead and cheek when we see each other. I was told that he didn't do that tell anyone else but me. I don't want to overthink it and ruin our relationship but I do think we like each other. He's really nice and we have similar interests and personalities. His best friend said that he talks about me all the time but he could've been joking. What do you think?
