<human>: Summarize the given text in a few sentences.

Back story is we separated a little over a year ago. Soon after she started using heroin. I did everything in my power until now to get her help, get her home, anything I could do to get her sober. I'm at my wits end. 

I have no idea where to go from here. Is it time to walk away? I don't think I will be able to look at myself in the mirror if I walk away when she needs someone to help her with her addiction. I'm just looking for any kind of insight or help. 

Thank you for taking the time to read this.
