Thank you for the info, that is helpful in order to understand the situation. I would suggest you read about the sex-starved marriage, about men's needs, and Zues has written many posts here from a man's perspective that can be really valuable.
I'm guessing that he felt very betrayed when you got pregnant, because he had said he didn't want that yet, and you still got pregnant. That's a big decision that you should both have been in agreement over. So now, he probably feels like you already betrayed him and he's not doing anything you didn't already do. That is what makes him not care about your feelings - he doesn't think you cared about his.
You said 6 children was what you had planned when you got married - do you think that you at 19 truly understood what that entailed? What would be required emotionally and financially? Was it his idea or yours? I think these are things you may want to look carefully at and try to see from his perspective. We often adjust our plans to fit with changing circumstances - was that what he wanted?
It is key to truly understand your partner's point of view, and treat their feelings with respect. In a M, in the day-to-day struggles and stress, it's easy to start treating your spouse poorly, as you already have realized.
I hope both of you get some information about what to expect in your state when it comes to custody and otherf legal matters. It can save you a lot of arguing.
Keep posting!
