My pregnant wife does not give me attention.
Why does that bother you?
I do not like the way she is doing things now. Before, she was more attentive to me.
A pregnant woman needs all the support she can get while she's carrying another life inside of her. Rather than focusing on what you don't have, focus on what you can do to make your wife's life easier while she's pregnant.
She always got her own way and makes me feel stupid.
That sounds tough, but I think you should try to be more understanding of your wife. Being pregnant is very difficult, so you should let her have her own way more often, if it helps her.
