Personally, I feel it helps to have a contingency option as you never know when the drought is going to bite hard. Keep it going, minimally.

I would cite being busy and/or very stressed out with some fictitious problem and extend the time between meet ups slowly. Or maybe say you are seeing someone for real and wish to see if the relationship would work out. Hopefully, you can resurrect this suspended relationship when you need some action.
