"I adored those dogs, but I justified their sacrifice to the greater good of a successful relationship."
What a complete idiot, and likely a somewhat sociopathic one at that. Why were the dogs not welcome? What does that tell this twit, as far as compatibility? Why were the dogs not placed with a no-kill shelter for adoption ... selfishness?
Love me, love my dogs. No ifs, ands or buts, as far as I'm concerned. If I'm ever forced to give them up, and it would have to be something incredibly serious for me to even consider it, the last thing on my mind would be to kill them.
Really. I can't imagine a woman putting to death 2 healthy dogs that have been loyal pets in order to be with somebody else, especially when they could have been given to a loving home.
And from a guy's perspective, if a woman said to me "you know Muffy and Fluffy? I'm having them killed so nothing will come between you and me!", I'd say "Uhhh, thanks but no thanks, and please don't call me again. You are a creepy freak. Get some help. Goodbye."
