She had no time for me today.
She says: that's perfectly reasonable. We have our lives that need attending. You can't be the top priority at all times.
I disagree that it's reasonable. It's not about being top priority, it's about being a priority. It's important to feel important. If you're permanently an afterthought you evolve into a convenience: a utility existing to serve specific needs when she's horny or lonely or simply wants to be distracted.
Until you spin, inward, downward, your needs unmet, your loneliness unaddressed, and a trapdoor opens below your feet leading to a very scary place. Where love becomes the most painful experience.
