Why aren't marriages lasting longer?

I separated from my husband because he was taking me for granted. He was very selfish I felt like a married single mother. He wasn't present, didn't help with our kids at all. We had 4 back to back I guess it got too hard for him. It took me two years to leave him it wasn't easy. When we got married I relocated 800 miles away from home just to be with him. I had no one, no friends I'm an introvert but I didnt go back home. I went to a shelter his family stepped in to help with the kids. I put my head down, worked two jobs until I closed on a house two months ago.

Now we split the kids every Wednesday we switch off. He's been begging to get back together but I love my life now. I learned to love me again and honestly I don't want love anyone else but me, my kids come from me so I count them as well. I just want to be a mom and a woman. Do what wanna do when I want to do it so I filed for divorce, custody will stay the same I don't want child support I just want out. I worked my ass off to get where I am today.

I opened up about my divorce to my family and the two friends I have. Nobody knew about it my issues with my husband was known but everybody kept telling me to "stick it out." When I told them they made ME out to be a failure. My uncle called me and read me the riot act about how marriage means nothing anymore, women leave for anything. New flash sir it ain't the early 1900s more men are stepping up with their kids, balancing fatherhood and employment, hell more men are successfully getting custody of their kids. Times are changing I dont feel like me wanting out is wrong. This situation isn't minor I was losing weight, crying all the time. I was tired of thugging it out for the kids they deserved a better mom, the current me. Marriages aren't lasting long because us women ain't taking no shit, no half stepping. I've been getting attacked left and right but I'm standing my ground I dont want to be a wife anymore!
