I don't know you, but this is what pooped out straight in my mind when I read your post:
Despite spinning plates and getting numbers left and right, deep inside you you're insecure and need your self-worth being constantly validated by those women and actions (spinning plates and getting numbers), as to say to yourself " Yea, I'm still desired" " women still attracted to me", but look what happened when ONE girl didn't feed your self worth: "it set you off and ruined your mood", and in other words, "Shattered your fragile confidence".
A truly confident man, with an abundance mentality, (as you claim to have ) will brush this rejection aside without giving it a second thought.
Your fragile confidence is the result of you not believing in yourself, of a low self-esteem.
(Now, maybe it's all BS , but that what it feels like. Correct me if I'm wrong).
