We have been married for 3.5 years with two kids, one of them just 3 months old. After my first son was born, we had a lot of issues and almost split. It got so bad that DCFS got involved and gave me and my mother the right to keep the first son until she takes steps to fix herself. She threatened suicide and also drove intoxicated. Finally, we got back after she took the steps to try and get out of her state (PPD). It was a rough phase but I supported her throughout. She stopped working and I took the lead.

She has always had a very rough relationship with her mom. Her mom was and is abusive, manipulative and an all out weird person. She lacks a good female figure in her life and has trust issues because of it.

My wife is never happy with me and constantly attacks me and complains that I don't do enough. She hates that my work requires travel and I have other streams of income. My parents and siblings live nearby and have been a pillar of support throughout these years and have taken care of my son(s) through out these years. In order to make sure my wife is set up when I travel, I hired an au-pair. That didn't work out. I got my wife a job through my contacts but she couldn't survive there and ended up fighting and left the company.

Now, we had a big fight after she returned from a 4 night stay at a hotel, which I booked since she needed a 'break'. She comes back and started to attack me saying I didn't take care of the house and her needs as there was no grocery when she returned. I mean, I was taking care of an infant while she was away and I did get groceries but again, she finds a reason to complain. Things hot heated up and she wanted me to leave the house. I called to cops who came and talked to us and told her that she can't ask me to leave.

She took my kids to visit her parents thinking her mom has changed and might help her relax but it was a miserable failure. I drove 6 hours overnight from Dallas to get her and the kids back and eventually flew them back to Chicago. These things are just a summary of what's going on but my main worry is - now that she says she wants to file for a divorce (maybe already has), can she take the kids to a different state? Will me travel schedule work against me? I don't feel safe leaving the kids with her for extended periods. She has texted me multiple times saying how she "fucking hates the kid". Her mom asked her to kill herself and my son. I don't want her to be close to her mom and be with my kids away from me for a long time. I'd like to keep the kids in the city I live in since there is a history of help and dependable people around us that have helped raise my kids.

This post has been longer than I thought it would be. Any advice is truly appreciated.

tl;dr - we are heading for divorce. I don't feel it's safe for my kids to stay with their mom. I have evidence that proves this. She wants to divorce and move to a different state - is that a possibility?
