unsocial, the good news is that you are able to analyze your situation and you know what’s missing in your life. Furthermore, if you got married you can’ be such a hermit 😉
I know a 19 year old guy in my family who is a “real” loner. He has no friends, doesn’t connect with his parents or siblings. He simply wants to be left alone (with his computer). His family has tried to reach out to him, but he is not receptive to anyone or anything. Bein Hazmanim he barely goes out of the house (just for davening). In Yeshiva, he has no chavrusas (his father pays someone to learn with him, but half the time he doesn’t show up). He wishes he could live on an island by himself where nobody would bother him, nobody would talk to him, nobody would offer him anything nor request anything from him.
I wonder if he will ever marry…
