For Clark's friends, Clark and Diana see each other not very often. Sometimes Clark goes to visit her and stays in London for some time, sometimes it's Diana who visits him and stays in Metropolis for a while, but she doesn't work there, so no need to fake she does. In true they see each other basically every day. Some days it's Diana who flies to Metropolis at night, sometimes it's Clark who flies to London, or they meet at the Fortress or where they want to.
The ID is basically for Clark's friends who live in Metropolis, while in London Diana can continue with her life. If someone tries to investigate and does it informatically, thanks to Bruce and Cyborg there are fake documents online. If someones goes there, he/she will see Diana living her life (in London it's not like they recognize her as WW when she doesn't wear her costume. Like I said I think she has already some fake ID of sort, because she has already one or maybe more houses). She could be said to work for Hessia, for example, so that in case of an investigation, Hessia can confirm that and inform Diana that someone is suspecting something.
And then we could have a story of someone suspecting and as usually it is with Superman protecting his identity, at the end Diana's ID will be safe, they'll invent something so that it will.
Another option: instead of working in London Diana could be a volunteer in war zones. In Justice League we already see her there helping people as WW, but she could go there as Diana Prince as well. Plus, with her going there also her being now god of war could be explored. This job of her would be very much true but still something she wants to do and that she would do anyway and that would explain her supposed long absences from Metropolis (even if her and Clark see each other anyway thanks to their powers). (Basically she helps there as Diana Prince, but when and if situations get tough, she switches to WW).
So, still living together, only not always in the same place. That is why I said theirs would be a not traditional relationship.
It's not like similar relationship don't exist, though, there are people who are married but still work in different cities and see each other only on week ends or even less (but in true Clark and Diana are only apparentely distant from each other, because they can see each other anyway whenever they want just by flying in seconds around the world and they can also settle together every night and return to their separate lives only in the morning xD).
Oh, and Clark would even have an excuse ready for when he will be away because of Superman, something like this: 'I went to London to visit Diana' xD
