When you put a lot of yourself in a relationship, no matter how long its shelf-life is – a couple of months, a couple of years, whatever – when you invest a lot in it, sharing, caring, loving, getting to know someone, getting someone to know you, your favourite book-movie-band-song, what gets you down and lifts you up, when you consciously try to remember the same things about the other person, it’s deep and intense and you think this level of involvement is possible only once in a lifetime. I’d hate to do all that all over again with someone else, you think. So much to show, tell, know, remember. Too much effort, too much to bother with again.
That’s bullshit, by the way.
Because no matter how jaded you are, and trust me I should know all about that, you don’t lose your capacity to love and to want to be loved. And as long as that exists within you, you can and will put in the effort. Because then it doesn’t seem like effort. Merely a matter of course that comes naturally.
