Im an introvert but married an extrovert and it's worked out well. 15 years! I have no idea how it happened but she took a liking to me and one thing led to another. I like to be quiet while she likes to talk a lot. She does a lot of outdoor activities like ski/surf/mountain climb etc... I do it sometimes but she understands when I don't want to. Maybe she likes that I give her the freedom to go out and do anything she wants while I've seen in other relationships the husband or wife need 'permission' from the other to do anything.
I guess OP what I"m trying to say is don't just look for introverts if you're an introvert. It can work out the other way too
