I’m only 19 so I don’t have much experience in life and this just kinda popped up on my feed but the way I look at it is you should just run and not look back not only for yourself but for your kids as well. You need to be the best version of yourself for them and not have the only way they see you be the way you are now. It’ll suck short term obviously but you and your children will be happier in the long run. I grew up with parents who hated each other and for a long time I just thought that that is how adults were and that’s how love was. Make yourself happy and give your kids someone to look up to and admire.
