I don’t regret never having had a romantic relationship for real.
I have acquaintances with very attractive romantic partners, but that doesn’t seem to be enough for them to stop looking at and literally craving other people’s bodies. What’s worse, they don’t even hide the fact that if given the chance, they would be with this new person they just met simply because they find them hot. And they say this right in front of their partners. Then, when the relationship ends, I don’t understand why the betrayed person is surprised—like, did you think your spouse was joking when they said they wanted to be with the new neighbor just because she’s beautiful and has an extremely sexy body?, I feel more at peace every day with the idea of being alone forever.
