Ahhh why!!!!!

Well of course you are going to cry. No matter how mean someone is to you if you have a life with them then it's gonna sting a bit when you leave. The important thing is that you get through it so you and your kids can be happy though. Get out and get happy. Good luck. 

In my experience with situations like yours, as much as you love him and want to be with him, you need to put yourself and your children first. The unhappiness in the household with a bad relationship can have a very negative affect on your kids. They know when mommy is sad and as they grow up they will think it's OK to either treat someone like that or accept that type of treatment. It's not worth staying with someone "just" because of the kids. Being pregnant and dealing with the stress of that type of relationship isn't good for your baby. Im sure you are a strong woman and though it will hard at first, moving on will be better for you and your babies. Good luck and I'll keep you in my prayers.

Think about it this way, you have a kid with him and carrying his second child. This on its own, is a miracle and a blessing. He should respect you and appreciates you. Not call you names and be such a jerk and only be good with you during sex. If you're miserable with him, why stay? You'll cry a couple of weeks and you'll get over it - and he will realize how amazing you are once you leave him. "You know know what you got until it's gone."

Letting go hurts sometimes, but when its for the best it will feel good later.
