Mav, I had a similar experience; my first wife had an affair with an elder (who also happened to be my employer)...nasty thing that ended up with committees from 2 congregations. She and he were df'd, and, as he predicted, they were reinstated in one year.
He asked me to meet him at a restaurant, to apologize, which he did (in a perfunctory and not particularly convincing way), but, yes, I accepted his apology (and, of course, he made sure that the elders knew that he'd "apologized" ). Even though I felt very ambivalent about it, I felt a compulsory obligation to forgive him.
Right after they were reinstated, there was an assembly, and at lunch break we crossed paths at the back of the assembly hall. He approached me, stuck out his hand, and acted like we were long lost buddies. A ring of about 30 people around us suddenly went totally silent, as they waited to see whether I'd shake his hand or throttle him. Again, I put on the front of forgiveness.
You can tell that I still have mixed feelings about that whole thing.
I don't know if that constitutes passive-aggressive behavior (in the particular psychological definition of the term), but, at the least, I think it illustrates how inconsistent we can be, even within ourselves. And if we can play such games within ourselves, then certainly we can play them with other people that we've "met" only via electronic communication (db, phone, etc).
Self-honesty is very difficult, especially when we were raised in a religion that discounted the worthiness of ourself, and emphasized loyal compliance to external laws, principles, and policies.
Carmel, hey man, sorry we missed you! But the Mongolian Grill is a bit above my tastes...Burgerville, maybe? LOL
When I get past this slug of work, I'll definitely need a rest, and we'll come over and haunt your premises for a day or two.
