First off if he is putting your child at risk, it is a deal breaker.
In matters such as this, you carried the baby, you decide.
If he is arguing and dismissing you, you have a real problem.
Don't think this will resolve itself.
It will escalate to him dismissing you in front of your child.
For goodness sake don't have anothet child with a man who is so dismissive of you.
A good man and father, doesn't do that.
Men like him are usually bully's, controlling, dominators.
It doesn't make for a good life.
I hope you work?
If you don't, I suggest you return to it.
Don't be vulnerable with a man who thinks he knows it all.
