What I miss the most about being in a relationship? The intimacy. Not (just) the physical, but the random calls about the fat guy you saw on a scooter. The “I bucked my toe on the bed” calls, the “I turned on the garbage disposal, and it splashed back on me” calls.
Miss that.
It's so selfish to enter someone's life, see that they're a loving, cheerful, and good person, and decide to ruin their peace because you haven't dealt with your own issues. Leave people alone if you have no intention of showing up with sincerity.
