Are you coming back? You poor girl. Twenty and thirty questions at a time. But this is a cool thread.
Seriously, if you are still responding:
You meet this guy, he is perfect in every way, sexually, romantic, attentive, the two of you never lack for something to talk about, little angels drift above and sprinkle sparkly stuff down on the two of you when together.
This goes on maybe for a while and then suddenly he does one thing that is an absolute deal-breaker, you think, "this can't go on, it must end now."
What would be something that would be the ultimate deal-breaker even if everything else was perfect? Bear in mind, it could just be one, like the absolute, or if could be more than one thing, listed like a lightning bonus round. Thank you for your response.
