Don't want to make a tit

[shitpark]

Of myself. So going to ask a stupid question. I've been online dating for a few years now on and off, and think I've lost the knack of recognising if a man likes me. So I'm going to describe how someone behaves towards me.

Ha. Didn't finish.
He looks me up and down and I've caught him checking out my legs, and body in general every time I see him
He goes out of his way to be helpful to me, I thought this was how he is - a nice guy, but it seems to be aimed at me only, can't say what he's done, it's very outing
He smiles at me, laughs at my ridiculous jokes and when he does he looks directly at me, no matter who else is there. If someone else makes a joke he looks at me when he laughs or smiles, I know because I look at him .
He always sits near me or opposite me, even though the room is empty.
He recently told me my perfume smelt nice, and leaned forward to tell me.
Constantly touching me, holding doors open etc.
If this is how men generally behave when being just friendly, then I'll accept that I'm sad and need to get out more to meet more men irl, if it's something then I'll enjoy the frisson. It'd be unethical to date him.
