If he thinks that 4 kids are too much, he needs to date a childless woman.

You are not stuck, you can end this relationship, if that's what you want.

I understand this. My husband is similar in attitude. I have three kids and he has one. His son is very poorly behaved, even the teachers say this, so it is not only my opinion. My kids are mostly good. Also, their teachers give awards for their good conduct, the neighbors invite them to play, and they have many friends, so this is not only my opinion. My husband tells me often that we would be ok if my kids were not here. Yet, he allows his son to act terribly, to make our home like a circus, and this is ok to him. It is not ok to me or my kids, but I cannot say this. I do not know why some people act this way.

Why do you feel stuck? If someone doesn’t like your kids it’s not good for your kids to stay.

Why do you feel stuck? Do you work? Are you financially dependent on him? Fix that and you won't feel stuck.

This is great site to find others that are going thru similar situations and the advice from here is often well thought out!

I don't post much, but I sure do enjoy reading what others have to say. Sometimes all I need to hear is that I'm not alone in my situation. Sometimes I see another's post, and relate so much and take the advice given into my own situation. Let me tell you, it has helped! 

It definitely looks as if you are becoming bitter towards your spouse. I would suggest having a heart to heart talk with your spouse about your feelings of unequal attention towards all the children in this situation. Tell him what your expectations are in regards to how the adults in the household should be interacting with the children in the household. Just because you play a game with his kids, doesn't mean that he feels like he should in turn play a game with yours. This may just be a lack of comunication.  

Next time he tells you that 4 kids are too much, tell him that that is fixable. If it's your house or apartment, he and his kids move out. If it's his house or apartment, you and your kids move out. 

Are you sure your kids are perfect? I don't mean to sound ugly but maybe he notices little things you do with your kids that annoy him the same way you notice how he babytalks to them.

Now after considering this, understand that if your children are decent, wellbehaved children as you describe, then he is probably projecting resentment onto your kids which happens a lot. Or at least it's mentioned a lot here. He is not a good parent and his kids aren't turning out and it becomes even more glaringly obvious when your kids are around behaving. He is bitter and instead of changing or mimicing your parenting, he would rather sulk and stew about it.
