Help 🆘

My SO and I got married when I was 18 and he was 20. I got pregnant my senior year of high school (I later found out his mom and grandma pressured him into marriage). It’s been 5 years and we have two kids together and each year we fight more and more and the last year he’s said he was filing for divorce 3 times. He’s a narcissist and thinks he does no wrong and he is never home to help with the kids or anything around the house. I’ve contemplated leaving and moving back in with my parents but I’m just not 100% set on doing so. He misses almost al of my family get togethers but throws a huge fit when I don’t want to go to his. What do I do? Any advice is welcome!!!!!
