Lois and clark are fighting because of the secret reveal, and later he finds her and is depressed about a bad rescue and tells her to go home because he can't handle it right now

Was it When Friends Become Lovers by Kathy Brown and Demi?

There's a scene like that in this story, but she goes to find him after a bad rescue and he tells her he's not very good company right now and she should leave (she doesn't)

Yay ! Thanks!

You're welcome!
