Thanks Andrea, I think I could have summed it up more easily by saying, "for me love is what makes it worth staying & fighting for".
It's not enough on it's own so if it were the only "Pro" on my pro/con list, I'd be gone. It also doesn't "make up" for a lack of anything else, like respect or honesty. But when everything filters down & my pros/cons are running about even.... then I factor in the emotion.
