<human>: I'm a 23/M she's a 23/F, we've been together for four years, suddenly we've stopped having sex.  It's been three months, and I'm getting confused.  She claims it's because she's "Trying to get her life together".  Which I would be totally fine with, if any of her rules/new behaviors made any sense.  However, they don't.

I guess in her mind "Getting her life together" means.
-Buy a kitten (She has two cats she left at her mom's house when she moved out.)
-Work a job she constantly tell me she hates.
-Saying she only wants to hang out on the weekends, unless she makes the plan, then it's totally ok to hangout on the weekdays. i.e. date night.
-Relying on a roommate for rides everywhere. To and from work, to the grocery store.
-Taking vitamins
-Not having sex

I love her, but this is putting a strain on a formerly awesome relationship.  She says there are more important things in a relationship than sex, and I agree, but taking a piece out of a relationship that was formally there seems weird to me.  

She also seems to always avoid a conversation about our relationship.  That pisses me off because when I have a problem I am direct, honest, and forthcoming with my issues, she however says she's ok for weeks, and then finally tells me the issue LOOOONG after it has happened.

She says it's not a healthy relationship because when I'm not around she's depressed.  I'm trying to be understanding, but I just don't know what the f is going on.

Is she just not into me anymore? 

Any advice would be greatly appreciated.

Can you give me the gist of the text in a nutshell?
