I wonder why I should get married. What is marriage for me? What’s the point? Marry, be happy, and then die. Nothing interesting for me. Also, having a partner seems beyond my capability. I am not as handsome and physically attractive anymore, so it makes sense that I have no reason for a woman to love me. There is no evidence that supports the need for me to marry and have a partner.
This is a question for a couples therapist or a psychologist, really. There’s only so much that the Internet can do to help us understand ourselves better. With that said:
Marriage isn’t for everyone. We all have our own likes and dislikes, which means that marriage will be great for some people and a bad idea for others. “Your mileage may vary.”
I’d recommend that you meet with an expert (if you’re able) to better clarify the question for yourself and to better understand your emotions.
Also: I’m concerned by your suggestion that the only reason someone would love you is for physical appearances. This is a big assumption and definitely worth unpacking.
