A girl 'like'ing you only results in your being one of the few she fucks regularly. Doesn't mean anything in terms of a relationship for life.

The reason for all this BS, and really part of the slippery slope of the alphabet maniacs, is this idea that relationships based on 'feels' is the most important thing.

What comes from hormones/chemicals, can be got from a bottle, and lost with replacement hormones/chemicals.
