What if I just leave?

Is it possible to just... leave? Leave my kids and husband and like disappear??

We got married when I was 21, he was 30 and very much "settled". His youngest child was 3 when we got married, oldest already a teenager. He decided he wanted to "start again" and have more kids.

After a miscarriage and moving, being laid off from a job, and 14 months of struggling to conceive we welcomed our first. Life got hard. Bills piled up and we ended up in a 2 bedroom apartment living paycheck to paycheck. Then came our second. My husband tells me all the time how he feels like he went backwards in life. He's never downright said it, but I know he blames me and our 2 kids. He's a great dad, very involved and loving, definitely a better parent than I am. I dropped out of college after my first miscarriage and haven't gone back. I continue to stay stagnant in a career that I always intended to grow in.

I often think about just packing a bag, saying bye to my kids, and leaving. He would thrive as a parent and I truly believe his life as a whole would improve. Is it even possible to just.. leave? I wouldn't want to be tracked down and would want contact with to end immediately so the children don't have any confusion. Can I do it???? Would there be legal ramifications if I left them with their more than capable father???
