expressing a little about my recurring pattern in matters of love

I'm feeling angry at myself, and sad, for keeping on falling in love,
at various times, with a woman who it turns out will never want to
love me back, while completely ignoring that there is at least one
woman in my life at that time who would gladly love me back if I just
paid her a little more attention. I usually find out only much later,
when she has moved on.
