OK, then, thanks so far but I obviously need many, many more data... but en attendant, let's try the follow-up question about rebound relationships - do they ever last, or should they always be regarded as the bridge from {whatever drove you nuts about the prior one} to (achieving the state of not putting being with somebody above whom you're with}? My experience is #2, but I've never even come close to such a, well, eligible (to use a quaint unfashionable term) rebound...And what makes it follow-up is, are the Rules, or species-specific ritualistic courtship behaviors, whatever they are, different when on the rebound, or just one's priorities?
