How do I win her back?

Me and my ex moved in together, but we lasted 3 weeks due to working together, all got to much and I've sorted it so we don't work together yet she is adament on being alone, she's still living where we lived and I moved back to my mums 2 days ago, we talk briefly but I try and try and I get no where, a close friend to us both at work says we will get back together because its happened worse before, I've done nothing wrong an we are both to blame, will she not come round this time? What we have is great, we care for the elderly so I have a big heart, I'd do anything, anything at all.. Any advice on what I can do? Or do I jus leave her alone? Give her space.. But I'm scared she'll forget about me! She's a strong girl

Thanks :)

Give her space. If she forgets about you, then that means you didn't mean that much to her.

We broke up twice already, and the reasons were a lot worse, but she's said different things this time, she suffers from depression due to a loss, maybe she has had enough.. But work has been sorted so there must be some way on doing something? I feel so helpless because I've done nothing wrong and I have a caring nature so I just want to do something to fix it ya know? It's so hard Sitting here.. There must be something? Or I just give her space for a week or something? Mhmmm :(

People who suffer from depression can't be controlled or "fixed". She has to get help for herself from a healthcare professional. All you would be doing is aggravating her situation. Some forms of depression is a life time of constant treatment and there is no cure. All they can do is maintain it.
