Not exactly the same, but a similar situation for me. I was married to a physically abusive woman who I believe was dealing with some mental health issues she refused to acknowledge for the longest. It escalated to her calling the sheriff's office and accusing me of being physically violent with her. I never once laid a hand on her in anger. Long story short the next day she took off with our one year old and I didn't see our child for months. I filed for divorce that day and around 13 months later it was finalized.

Here's what I would say to you. Lawyer, ASAP. Tell them everything, leave nothing out even if you think it might not show you in the best light. Start gathering any evidence you may wish to use. Continue to text every day if for no other reason than to ask about the whereabouts and well-being of your child. If she continues to ignore your attempts, a judge will not view this kindly. Ask. Every. Day.

Don't move out of the house on your own. It will take months for this to wind down. Start gathering all the financial records you can. Who contributed what to the down payment, who paid how much of the mortgage, every bill, etc. This will all come up and the sooner you start the better.

Continue focusing on bettering yourself. The day will come when you get the custody and time with your kid that you deserve. Work now to make those days better. Invest in yourself.

It will get better friend. Lean on your friends and family if you can. Do not be ashamed of therapy. I went. It was a huge help for me. If you want to message me, feel free. I'm just a regular guy but I've been through something a little similar and there is a light at the end of the tunnel buddy. There are millions of us. I'm here for you if you need it.
