I'm going to complain about being tired to my pregnant wife
What is the point of complaining to her?
I want her to know how I feel.
She's doing something a lot more difficult. You should be there for her and not make her life harder.
Nah, if they can do more, they should do it.
It is unfair to ask more of her, even if she can do it. You need to understand the burden of being pregnant and do your best to support your wife. Complaining to her will lower the moods of both of you.
