Anyways, so I was at my cousin's party on Saturday and she has this cute cute friend. I've seen her in my cousin's pictures on Facebook a number of times so I was pretty familiar with how she looked beforehand and figured she'd be there. I wasn't entirely inclined at the time to talk to her though because I wasn't entirely interested outside of the physical attraction. Until I spent a few more hours there and went home, then I became interested more. Sort of useless at that time. Anyways yesterday I messaged my cousin on Facebook asking how old her friend was (they just graduated high school so I was just making sure everything was legal) and she said she was 18, then I asked her if she thought I was to old for her.
She didn't really know how old I was (been my cousin for like 7 years and we've talked less than a couple times before that party) so I told her I was almost 25 and she was like "idk her dad is very strict and would probably kill her." Now me being the rational person that I am said I wasn't that much older than her but she said 7 years apart was to much and that her dad was crazy.
So there's the story, now the question for you guys. I don't entirely know if I want to date this girl yet, I just want to talk to her first. But should I even bother now? She's 18, going to college (in state) and maybe not worth my time but she might be, so...
I'd have to do it through Facebook, at least at first because that's the only way I can contact her. Should I bother sending a message? I know what I want to do really..it's just I need more confidence in my decision and was hoping you guys could give some insight! I'm not even sure how to form the message without sounding like a creeper.
Personally I don't think her dad should care seeing as she's an advlt but I know how fathers can be so I'm kind of on the fence. I mean, she might not even like me so it might not even matter, I'd at least like to find out lol.
Oh and thank you for the JAHO (seeing as I'm not even trying to yet!) comments they're appreciated as much as dirt in the face.

On a side note, this is pretty much my luck with women..it's very discouraging and makes me not want to bother most of the time. I either get girls I'm not attracted to at all who get interested in me (not for a long time though) or I get interested in girls who either don't like me or something like the above story happens.
