Basically at a house party at mine, there was a HB8 that I managed to kiss close. We made out for a good 10 mins or so. Next day she added me on Facebook and we chatted a bit, and basically she says the night was a bit of a blur and that she doesn't remember much. I don't know if she remembers making out with me or not, I haven't asked her and I don't know if I should. Though I'm pretty sure she's found out either way about what happened through her friends.

This girl is a friend of a housemate, and I know her best friend quite well. She is possibly coming to a party or two during the next week. I wanted to ask, should I ask her out before this party or should I wait to see what happens at this party?

My intuition says second scenario. And my intuition is always right.

I dont know why do you want to ask her about it? I think she propably remember it and if not and you'll ask her about it she will feel very bad. So dont ask her and try same ways again and you'll see

Hah women can be so full of it. She remembers, trust me.

If you want to catch up beforehand just go for it once. Don't push just say "let's hang, I'm free xx night, up for it?" If the answer isn't positive, just say cool might see you around, then try escalate when you see her again.

Simple.

if she remembered enough to remember your name and add you on facebook then she remembers makin out with you,
i think you said that she added you on facebook if thats true then i think shes definately interested,play your cards right and your in ; ) plus if you have female friends in common tell them to put a good word in for you,social proof and qualification straight away there shes in the bag mate good luck

I could be wrong but an alarm bell rang in my head. It might be that saying that the night was a blur, is her trying to say that she was drunk and didnt know what she was doing. It might be a subtle way of telling you she's not interested. That has happened to me before, however, that was after I contacted her. So as it's the case that she initiated contact with you, might mean a different story. So hopefully its not the case. So I agree, just see what happens at the next party.
