You shouldn't be dwelling on a girl who thinks you're a creeper, but you shouldn't ignore it either. There is a good chance that she is just being ridiculous- but there is an equally good chance, that you sent off some message somewhere along the way that said "creepy." Take a step back... did you go to parties just because she was at them? You didn't approach her, but did you watch her from a distance? Were you a little too "mysterious?" These things can all come off as "creepy" when you would least expect it. The best thing you can do is recognize whatever you did that was supposedly 'creepy' (that is, if you DID do anything creepy... and be honest with yourself.) Make sure it doesn't happen again, and then ignore her. She thinks you're a creeper, get on with meeting other people.

As far as THIS party: If this party is going to interfere with your interview, it would be a good idea to pass it up, or leave early. Parties come and go nearly every weekend, but jobs are hard to come by these days.

Also, and I cannot stress this enough, YOU DO NOT NEED A GIRLFRIEND!! This is pressure that is put on youth these days. You cannot go into a relationship because you think you "need" one... This is completely unhealthy. Guys who tell themselves they "need" a girlfriend will end up compromising their values, beliefs, and crossing their own boundaries in order to "win the prize." Unfortunately, relationships that start by crossing your own boundaries, making compromises, and letting her "little" quirks slide, will end up in ruins.

You also, do not need to go to a party to meet new people. There are new people almost everywhere you go- school, work, the grocery store, any kind of function or gathering, whether it be a church youth group, or a boring book club. If you want to meet new people, you just need to look around, and work up the guts to start a conversation. When it comes to talking to women, you don't need a battle plan. Be casual, friendly, make sure the conversation goes both ways, and go into it searching for similar interests. Once you find something you have in common, a friendship will generally hit off almost automatically.
