Pre-Crisis they just recently had Baby Jon and were engaged not married. At the end of Crisis they seem to be married and apparently now have two boys.

At the end of S & L S2 it went out of it's way to establish it's not Arrowverse. Officially the fact that Clark, Lois, Lucy Lane and Diggle are the same actors is due to different Earth dopplegangers. It's a retcon but what they're going with. So Arrowverse Clark and Lois haven't officially been seen since the end of Crisis.
