<human>: Can you succinctly summarize the text in 1-3 sentences?

Married with kids, the marriage slowly became abusive on both ends, depression happened, I hit her, she pulled the trigger on her emotional affair, we physically separated, she's been with the guy ever since in some fashion, while she and I worked together to raise the kids.

Four years later our kids are all in school and she's still a sahm against my wishes while I support this broken family waiting for her to get herself together, because I don't hate her. I can't say love, because I'm not sure I know what love is outside of how I feel about my kids and family. 

Now she tells me she wants to work things out. My family will support me either way, but tell me I really should get out.

We both feel like we need to be won over, we're both probably equally right and wrong in that regard, but there's nothing she could tell me that I'd believe to be true anymore that wouldn't break my heart.

I have to divorce her, I know this, but I need to know what a loving healthy relationship looks like, because I really don't know. I've never seen one.
<bot>: What does a healthy, supporting relationship look like? Does anyone have a good book or some other resource, because I honestly have nothing to model it.
