While talking to a friend about love recently she asked (hypothetically), "I guess that's the eternal dilemma: Is the probable pain worth the certain (though perhaps fleeting) joy?" and then answered herself with "Fuck if I know!".
And it's true, we don't know. For me it's a sticky subject. I grew up in a community of people that says "I love you" at the drop of a hat in a family that says it just as often. I believe it's all around us but it wasn't until some interactions in young adult hood that I realized not everyone believes in the ideas I was raised with. It's not that they (or you, perhaps) don't love, it's just expressed differently, acknowledged differently and sometimes not at all. To those of us that love freely this is heartbreaking. How ever, the intensity of people's love is what makes me uncomfortable and sad. I wish this wasn't the case because I start to self-judge as I realize I'm close to the category of those that don't express love at all. While I saw "I love you" to those that love me, I don't always feel the acceptance and the joy that they express with me. Why? I have no idea. It's just another question that keeps me up at night.
It's not that I haven't fallen in love or that I don't have unconditional love in my life, it's that I don't seem to have it in the volume that others claim they do. I am a realist and a rationalist. Perhaps I am rationalizing love too much. Anyhow, think on this question from thoughtquestions.com because I need sleep.
