My pregnant depressed wife is driving me insane.
Why is she driving you crazy?
It's driving me insane because she is very grumpy and I can't take it anymore.
Have you tried to show her some support? Pregnancy can be really hard on a woman.
Why should I support her? If I leave her now I can find someone else easier.
I get that it is frustrating that she is feeling so down, but she is your wife. Instead of looking for a way out, you should try to help them through their emotions first.
