Marry another introvert. Mine is outside enjoying his solitary car washing and lawn grooming and I am sitting here with FSU and a cup of coffee and we are very happy with that. Every relationship I ever had before him was an extrovert. Magnetic big personalities--extreme extroverts. And I would be so into them and then, very quickly, they would exhaust me and I'd just want to go home. Until I met my husband (through a friend), and while it took awhile for me to be into him, he did not ever exhaust me. And he was exactly what I needed.
