If she isn't clingy, that's rare with my experience with women.
Bipolar is a bunch of crap, don't believe that, it's called mood swings, and believe me, I KNOW moodswings, my g/f had irregular hormones which caused her period to last up to five months.
If she's hyper, she's probably easy to make laugh, which girls love usually.
Non obsessive is ALSO rare with my experience. XD
Most girls are hurt easily.
If she's weak for a romantic guy, write her poems and stuff(From my experience, this will sweep them off their feet in shock and surprise if you don't normally do it.)
A way to find out if she's jealous, if you usually talk to her when you're upset, talk to someone else about it and make sure she finds out. Drove my g/f crazy.
Outgoing, if she doesn't tell you everything, then..well...not much trust, from my experience.
If she isn't talkative, make her talkative, long distance relationships thrive on conversations.
Shy, if she's really shy, do things that'll make her blush because they shouldn't be used to hearing it, it's automatic point scoring.
Antisocial, good for you.
If she isn't distant, that good for you too.
If you're trying to keep her and keep the relationship strong, from my experience all you can do is make her want you, do things you don't normally do, draw her things, write her poems(They don't gotta be good, because most girls will love the fact that you tried, and if she asks why, just tell her you wanted to make her smile.), ect, stuff like that.
If my 'advice' sucks, I apologize, I'm merely speaking from my experience in attempts to help.
