I'd recommend, before you do ANYTHING, to decide what your # of "strikes" is going to be as you go thru this. I always try to get people to do this AHEAD of time, before any re-contact happens, so that they're "calm, cool and collected," as they say, but you don't have time for that now.
Decide if you're willing to accept:
- ONE strike, so long as he self-confesses it?
- ONE strike, so long as he answers you truthfully if you confront him about it?
- TWO strikes?
- ZERO?
- something other??
Then, once you decide what you are willing to accept or not, re-confront him and ask him "Has she tried to contact you at all since Saturday?" -- and see what he says.
