OP, I really don't know where to start.
From this thread and your previous ones, it's clear that you are a victim of domestic violence and abuse.
This man is horrible and treats you like absolute shit. This is not a reflection of you, it's all down to him.
You cannot fix him, love him into being a better man. The situation is out of control and it will never change.
I'm sure your self esteem has been eroded and your strenght battered. You are at a stage when he has ground you down so much, you cannot see the woods from the trees.
He doesn't want to marry you and that is actually a very good thing. You would be guaranteed a miserable, abusive life with him.
I understand you want love, a marriage and the desire to have children can be all consuming but you will not find your happy ever after with him. Never and I'm sure you would want the absolute best for any children you may have. Be honest, you know that this environment isn't the place to give them that.
You need to re-learn your worth, who you are as a person and understand that you deserve so, so, so much better.
Consider the freedom programme, contact women's aid, get counselling. Please, you owe this to yourself.
On e you leave it will become easily, you will start to see how truly toxic your relationship has been and that not all men will treat you like this.
In a year or two, your self esteem could be back to a health level and you could even meet someone and have those child you desire and raise them in a healthy, happy, safe environment- surely that is what you want. Not this.
You have tried to leave before, try again. I know it's hard to break the cycle but you really do deserve better. Friends, family,therapists and domestic violence organisations will help you through this. You just need to let them.
Your happy ever after lies elsewhere and you'll never get it if you don't leave. There are strangers on the internet who care more about for happiness and welfare than this man. Please see it for what it is and get out or if you can't at least start to make the steps towards leaving by reaching out to women's aid.
