[Grammar] I could do with a new girlfriend.

[alpacinou]

What's the corresponding informal expression in American English?

Sorry but can we use corresponding as a synonym for equivalent?

corresponding isn't strictly the right word here, in my view (some may disagree).

equivalent is a better choice.

You might wake alone.

I speak while I'm sleeping. :-D

Say "I talk in my sleep."
