Be careful trying to read anything into what your ex says or does. In fact, just don't do it at all is probably the best policy, as you just cannot rely on anything a WAS says or does. You know: believe nothing they say and only half of what they do as being true.
The OM playing surveillance is just typical and to be expected -- seriously, would you really trust someone who has already proven to be capable of infidelity, even if that offense was done on your own behalf? No, the both of them now have to look over their shoulders constantly now -- not a swell way to live, is it?
