<human>: Can you provide a brief rundown of the text in within 3 sentences?

So I made a post about this on Advice animals, I thought it would be cathartic, but the situation is just getting worse.

My wife of almost 9 years (together for over 10) left me and our two children about 3 weeks ago. Since then she has been busy working at her new job, that I encouranged her to get to help with her depression and other issues. She's also been sleeping with at least one other man that I know of and hasn't bothered to be much a part of our childrens lives since she left.

I'm not saying that we've had a perfect marriage, far from it. But if you would have told me the morning that she said it was over "hey, your wife is going to leave you today." I would have laughed in your face.

She has had a history of mental illness, and I know that it's probably a big part of what is happening. But I cant get past that even though she might not be in control of her mental state. It's her face, its her body. It's her that's putting my family through hell right now.

This woman was my best friend and companion in life for a decade, we shared everything. Now I'm all alone and trying to figure out how I'm going to raise two children alone.

I'm not sure what to expect from posting here. I've had a great group of family and friends try to help me get through this, but I can't get out of this depression. To me it's a testament to how much she meant to me that the only person that keeps coming to mind that I wish could help is her.

My kids cry and miss her, a little more each day. My youngest is still too young to fully understand, but my oldest is aware of whats happened and he has been so strong and amazing that he keeps me going.

thank you to anyone that read this and could make sense of what I tried to express in my ramblings.
<bot>: Wife left my and the kids to run off and be single. Now I dont know what to do and how to feel.
