Does my mums boyfriend want to have sex with me?

Well for a few months I have been wondering does my mums boyfriend like me in a sexual way. We was out a few weeks ago drinking and I went past him to go to the toilet and I was close to his legs cause he was in the way and he slapped my bum. he always calls me gorgeous but never when anyone has been there which has made me feel suspicious. He also said I look like a doll so I said ‘why’ and he said because you have a dead perfect face, he always touches my face. He has said a few times to me that I should wear a skirt like if I’m going on a night out and I say what should I wear he goes ‘wear a shirt, bet you’ve never wore one have you’ also someone touched my face about a week ago and I said to him ‘why does everyone touch my face’ because he was near me and he said because you’re gorgeous, he says I get on better with him than his own kids. He said he has adopted me, do you think he is just trying to be nice and treat me like I’m his daughter or do you think he likes me in another way? Also yesterday when he came home he was a bit drunk and tried to lick my face but I moved out of the way and he licked my eye instead, I thought he was going to kiss me. He literally ran up to me as he was coming through the door and nearly knocked me over then licked me, I don’t know if he licks me because he wants to kiss me and he does that instead so it doesn’t look that bad, my mum didn’t see so I think that’s why he ran up so he could do that without my mum seeing, I haven’t told my mum about anything that he has done up to now, he has hugged me a few times but that is normal. He always seems to do stuff when no one is there. Sometimes I think he doesn’t like me but then he will do something which makes me question does he like me because some of the things that he does are a bit odd and what you wouldn’t really do/say to your girlfriends daughter, I’m 18 by the way so I’m not really a child. I do think that he might end up kissing me especially when he is drunk, he always gets really close to my face and I think he might try something one day.
