was I wrong to leave? please help!

** This is long, my apologies but I'm in need of help!

My husband and I have been married for 7 months and October 10th made a year together as a couple. Since we started dating he's been super controlling, possesive and very untrusting (I assume from past girlfriends and I just get the blame for it). Upon finding out I was pregnant, he really didn't work a real job but for a month and then quit. He also worked somewhat with his dad (he can never get fired, it's his dad). He makes $140-$240 a week and blows it on McDonald's, UFC fights, etc. instead of saving for bills we're 2, almost 3 months behind on. He knew he needed a good job but quit the first one he had and didn't look for another for a long time, now, that I've left and said I want a divorce. He's been waiting on a job that is supposedly going to happen for 2 months now and working with his dad on and off just for blowing money I'm guessing because he hasn't saved a penny for overdue bills or upcoming ones. Aside from that, he rarely helped me with our newborn once we got home. I can recall one time she started crying and he handed her to me as well as saying I don't want to feed her it takes too long. I was 99% of the time ALWAYS the one to get up and take care of her needs (with the exception of him washing her bottles and doing stuff maybe a few times) and if I ever asked him to help he'd get very frustrated, same thing if I had just put her down and she made one little noise indicating she was waking back up... I tried telling him many times I wasn't happy, that I didn't feel like he truly loved me and something needed to change but in our last argument he told me what is the point in making effort. Point blank I wasn't truly happy. Was I right to leave and say I want a divorce? I love him but that's not how I want to spend the rest of my life. I feel like if I get a divorce I'll be letting God down. He keeps telling me he loves me and our daughter more than anything and if I come back I'll see a different him for the rest of our lives but I'm not sure if I believe him. Now that I've left, it's like he's in denial about how he treated me, how he didn't help or look for a good job. I'm so conflicted. TIA❤️❤️
