First kiss

It's taken me ages, but I finally feel complete when I'm on my own. I have emotional support, attention, fun, respect, laughter, hugs, good sex.

However, there are other things I can't have on my own.
Help sometimes when I feel like shit.
A nudge when I'm being stubborn.
Homemade food when I'm exhausted.
Interesting stories I haven't heard yet.
Whispers in my ear.
A ridiculously romantic first kiss.

So if you are not planning to give me any of those things, what reason do I have to invest time in you when I could be investing it in myself?
