I need advice ladies

I been married for 1yr to my high school sweet heart but we known each other since 8th grade and we started dating on and off during high school.. my senior year I got pregnant by him.. I loved him at the time and we had our baby.. I had my baby April 2015 and I graduated high school June 2015... in October 2016 we got married.. I honestly thought it was the best decision I made back then but now I just see how I was so stupid I was 19 and married!! Soo years went by and now I’m pregnant by him again with our second baby and during those years yeah we had problems like every relationship does and I didn’t think much I loved my family.. I’m 34weeks pregnant right now and I can think about is how we constantly fight everyday.. wether it’s bc he plays his xbox when he come home from work everyday and doesn’t help me out around the house or me “always bitching” the point is this pregnancy I have been crying EVERYDAY bc we argue and I’m just so done.. I care about my baby I’m caring inside me and I know all the crying and fighting isn’t good for him.. I want to leave him but I just don’t know how.. I want us to be this perfect family and we are Far from perfect... I don’t know wether I should stay with him and just fake smile for all the pictures my entire life.. I keep thinking about my kids and how they will just see and hear us fight like we do everyday.. I don’t understand how some men are just the sweetest to their wife’s during pregnancy and mine is just like whatever about it like if I wasn’t carrying his kid! I’m afraid he’s going to be premature if we continue to argue everyday.. I’ve had enough I wish y’all could see the pain in my eyes and regret I have of marrying a stubborn man.
