Not all men act like this.

But also not all men understand pregnancy= there child. That sounds stupid but it true if he hasn't had any children before maybe he just didn't understand how much it ment to you.

Also its not just men. When I was pregnant with my daughter I was not attached to her at all untill weeks after I had her. In my mind she was a baby I didn't know so it was hard to care.

People can just be weird... You would probably be better off seeking support from another woman you are close to that has had a baby before.
