She said her decision was based on my behavior once she dropped the bomb. The whole begging/pleading/cards/flowers, etc... stage.
I can see this point of view. Especially from a woman's standpoint, some guy they had a relationship with, either a short on or a long one, that they lost attraction for, that they now blow off, treat like crap, maybe cheated on, who tries winning them back by crying, professing their love, getting emotional when they don't or won't show love back, is not an example of strength, and confidence, and self respect that are very attractive qualities to someone of the opposite sex.
Take that one step further, and get depressed over the situation, and I can fully understand why a woman or a man would quit that situation. Unhappy people bring the party down. Confident, happy people, doing interesting and "new" things, attract others who want to enjoy the excitement?
Life is short. Why fight the resistance? Is it not more fun to throw up the spinnaker and sail down wind?
