<human>: Condense the text into a few key points

Hey all,
So I'm 21M and she's 20. We've been together for almost 2 years now and we've been perfect. I mean we generally talk about anything and everything, but lately she doesn't want to do things, she doesn't look after her health: for example her sleeping pattern is "wake up at 1pm sleep at 6am". Always complains about back pain and being tired, we recently went for a walk which was 2kms and she was complaining after that, which isn't very far at all..
Things that didn't annoy me before now do, she wants misses at every red light when I'm driving, kisses when we go to the shops whereas I want to hold her hand and not PDA. 
We barely go out and I go to hers and we watch tv, but she doesn't sleep so when im trying to fall asleep at 1am her light and tv is on. Sometimes she talks to me like I'm an idiot, we were planning a trip with her friends (who I don't really talk to) and we paid $100 deposit. It came to a large amount and she said "it's ok we get our deposit back" and I said "no we get the bond back, a deposit is to just hold the house so they don't book others in it" and she snapped and shouted "we get it back! It's a DEPOSIT" and I explained to her what a deposit and bond is. Anyway that bugged me too. 

It feels like I'm writing a list of things that annoy me and it's getting pretty long..

Personally as well I like time to myself and with my friends, I feel I don't get this as I'm working and studying, when I get home I want to chill out but it's either see her or friends and I disappoint someone if I don't do either of those. 

And also she is my first girlfriend and I feel as if I'm missing out on experiencing others. I mean I've been hit on recently and it's very flattering, she gets hit on all the time and I feel jealous, she doesn't when I get hit on. 

Ahhh someone be my therapist haha. 

End of my vent.
<bot>: I'm (M21) feeling a bit over it all after being with F20 for almost 2 years. First girlfriend, first love, first sexual relationship.
