<human>: Could you distill the essence of the text into 1-3 sentences?

I'm not sure if I should get into too many details but last night after work, my wife told me she is leaving me and our two kids. This came out of nowhere, we have a very happy marriage and we just had another baby a couple months ago. She loves the kids so much that she only ever leaves them when she has to, like for a dentist appointment or something. She's never spent a night away from them, even when I've offered vacations or even just a night away for only her. She didn't give any reasoning and was very cold in the way she spoke to me, like it was a business transaction. 

What do I do? She has either blocked my number or gotten a new phone number. Deleted all other ways I could contact her. All she brought with her was her car and clothing and a few other small things. I did call her parents who I would say I have a very good relationship and they told me that they had only become aware of this last night, and they have been in contact with her, they're sorry but they need to support her. 

She said I'll be served with divorce papers in the coming weeks. She didn't tell me why she was leaving. I know that I need to "lawyer up," but beyond that, what can I do here? I'm not willing to just give up on the life we have together.
<bot>: wife left me and our young kids, blocked me from contacting her and is apparently going to have me served with divorce papers soon.
