My husband is leaving for a whole night soon and I don't want him to go.
Why don't you want him to leave?
If he left I couldn't sleep alone
There's nothing wrong with you asking him to stay home because of sleep problems on your end. That being said, you need to ber eady for him to say no if this's something important that he needs to do.
I thought you were going to tell me that I'm crazy. Thanks for listening.
No, you're being a normal human by wanting your husband to stay and so you should have that conversation with him. He may just agree to stay for you.
