Does he actually like me as more than a friend?

I don't think there's any way for you tell if your friend likes more than just a friend only based on what happened last night at the Halloween party since you teased him the entire night by what you wore, plus you said nothing when he put his hands inside your skirt nor when he held you tight enough against him for you to feel his penis. What he did is what most guys would do at a party when the girl friend he's with is half dressed. In order for you to know if he likes you, he'll have to show it some other way besides respond to your teasing. You know, there were another 1,000++ ways you could have dressed for a Halloween party besides as sexy as you possibly could. The fact that he tried to kiss you was no doubt because he probably thought you were open to his advances based on how you dressed for a hanging out with him. I'm sure he was just turned on by your outfit because if he wasn't, then he's not a normal guy. Most all guys would, including me. :-p If you want to know if he likes you more than a friend now, notice how he is around you from now on a compared to last night and how it compares to the last time or two when you hung out before last night. Then you'll know if he truly does.

I certainly wouldn't have done any of that to someone I didn't like more than a friend. That said, some guys (especially when under the influence) would do that to anyone they thought hot, friend or not.

Of course he liked you, you basically looked like a slut. Halloween is a way for girls to show off their bodies, get really drunk and seek attention from guys. It's no secret. Were you drinking? He was probably just "calling dibs" on you because you were the hottest girl at the party.

It sounds like he just thought you looked hot that night. He could like you but it just seems like physical attraction to me. Usually when guys like you, they don't go straight to feeling your ass and show a different connection.
