<human>: We've been married for more than 10 years, no children. No infidelity on either side. We've had our ups and downs, as we've both struggled with depression and difficult childhoods. We've lived through cancer and deaths in the family, together. 

Last month, she left. She had been depressed and distant for a while and I was hoping we would recover from this. She decided she needed to find her purpose again, she had lost herself. She says she loves me but cannot love herself anymore. I love her too, but now she's gone. 

I asked her what she expected of me ("nothing"), what this was ("trial separation"), how long it would be 1 year, 2 years, 5 years ("can't know that now"). 

After she told me all this, she packed a bag, got on a plane and flew to the other side of the country, to live in the city where we had met.

It appears she intends to find work and pay her own way, though we have joint finances. We were pretty much living from contract job to contract job and in debt before. My work pays well when I can find work, but my wife hadn't worked or earned income since we met. 

I am in shock, unsure what to do next. I don't expect her to come back any time soon. I'm not sure there's a relationship to come back to, it seems to me that despite our love for each other and the effort we put in we were not able to make it work in practice. 

Now I am torn between turning a new leaf in my life, as it appears she has done, or waiting for her to "find herself" and return. The latter seems insane and likely to lead to disappointment for me. But if I give up and don't wait, then I feel like I'm giving up too easily on 15 years of my life.

Can you condense the text into three sentences or less?
<bot>: Married 10 years, difficult marriage but based on love and respect. She was depressed and left me to "find herself". I'm not sure what to do next.
