What is reasonable and what is not?

[Startingover2]

I said he will not be in my life unless he cuts all ties with OW. Plain and simple. Either you are in or you are out.

He went on to tell me that I can't keep him from his daughter. I said she will not be born until March. I will keep him informed between now and then of how the pregnancy is going. After that we will work out visitation.

I told him I was getting stressed and had nothing more to say.

Thank you for the great responses. I am usually so worked up that I say things that I shouldn't and react way too much.
