There's this guy, every time I talked to him, 90% of the time, either I look at him or not, he will gaze deep into my eyes while talking to me. He only dart of his eyes to his right on and off when he's trying to think on what to say next, other than that, straight into my eyes, never budge. I read that if a guy likes you he will gaze into your eyes during conversation. What are the chances that he's interested and not just being polite? Of course, he smiles a lot too if we talk about something casual, and yes I caught him staring at me (while he walk passed by me) waiting for me to look over just so he could say hi with a smile when I looked back.
Yes, I also think that the intense look deep in somebody' s eyes is a proof of interest. Specially, when it is combined with smile and change in the tone of voice! I think you already know the answer! He is attracted to you...! Now, you should show him that you are attracted to him too.
I always do that when I like a girl, be it as a friend or in a more romantic ways. When talking, I always look into her eyes. So we can be pretty sure he likes you, now you only need to figure out in what way. The smiling, staring indicates he may like you more than a friend.
i think he's probably attracted to you...honestly for me I'm not sure if I do the same deep gazing when I'm talking to a girl I'm attracted to (maybe I do without noticing it) but I do try to maintain eye contact until the girl breaks it.
does he do this with any other people, if you have noticed?
To be honest he does like you and this is just one sign to show that he is interested. Also, its the polite sign and not the disrespectful type. Some of us do this because if interested you will look into a woman's eyes instead of looking other places. Plus you are having a conversation with each so its the right thing to do is pay attention to and not the surroundings. Especially when he is interested in you.
