Everyone knows relationships are hard work. Everyone knows that relationships hit roadblocks and whatever the fuck else. Fucking why. What’s the point? Be with a person that you mostly tolerate most of the days that you exist? And even then, they still might betray you in a horrible way. I’ve dealt with a lot of pain and stress and loss in my life, and when the happy shit gets sour, I just don’t fucking get it. Why not just live my life fucking off and dying eventually.
It’s a viable strategy. Most people seek comfort in the presence of others, but you can have that with friendships and occasional hookups just as well. In fact most long term relationships I know really revolve around raising kids more than anything.
