<human>: My girlfriend is becoming increasingly lacklustre, sleeping loads, and always seems to moan about things that she never gets round to dealing with. 

I love her to death. She's funny, beautiful, thoughtful, caring. But she's lost her zest, and it's dragging me down. We've talked about it, and she's considered the fact that she might be depressed, but never actually deals with it. And she moans about her weight all the time, but will always find excuses not to exercise or eat healthily. I'm as encouraging and supportive as I can be, even being her personal trainer when she tries to get fit, but she gives up so easily.

This is all really difficult for me, especially as I'm a really motivated, self-employed guy who wants to squeeze every moment out of life. And I want to do it with her. But I can't do that if she's always in bed, or sitting on the sofa, not wanting to leave the apartment. I've tried talking to her, and she always responds well. But only for about 72 hours, and then it's back to the same patterns.

The things stopping me leaving her:
- I still love her, completely.
- She's pretty dependent on me, socially, emotionally etc. 
- After all this time we're fairly financially "linked", and it would be messy.

But I want to be with someone who has my dreams, ambitions, and energy. Not someone who's going to wake up in 10 years and realise she's wasted the best years of her life.

What do I do?

<bot>: My girlfriend is lazy and wasting her life. I'm the opposite, and I don't really want to waste any more of my life with her.
