Coming from another introvert who is dating another introvert; dating an introvert is the best. I've dated extroverts before, and there are definitely perks to those relationships! When push comes to shove, though, introvert-introvert relationships take the cake.
1. No forced social interactions
Need I say more? If you say you aren't ready to socialize, they completely understand and respect your need for mental preparation pre-social interaction.
2. Adventure time
Group things aren't a thing, but being a small gang that has fun adventures all on your own is a thing. It's so much fun to "just go" and do things that the two of you love doing! Most of the time, no one else even notices when you've slipped in and out real life for your adventure time.
3. A whole new world
When you start dating someone who also spends most of their time by themselves, cultivating their own interests and working on their own personal projects; then you get to enter their rich, multi-faceted world of interests. If you find a fellow introvert who has similar-yet-slightly-different interests than you, the cultivated world you're being introduced too will probably fascinate you and introduce you to new movies, music, art or websites you might never have found but will probably love.
4. Angst
Most introverts deal with anxiety in social situations that extroverts don't feel, and if they feel "social angst" then it's easier for them to understand your social and generalized angst.
Finding someone who really understands the feelings of anxiety makes facing the world a much less daunting task. It's also good to have someone who understands both angsty feelings and you specifically because they'll help you calm down when you're being reasonable but still call you out when you're being unreasonably angsty.
5. Alone time
While going on adventures is fun, sometimes introverts just need alone time and dating someone who understands your need to go off on your own for a little bit is such a blessing. They understand that your alone time isn't because you're tired of them, it's not because you're bored of them, it's not even because you're mad at them; it's just because you need to recharge, take a deep breath and not talk to anyone.
When an introvert's interests and passions are shown to someone else and the introverts take the time and energy to open themselves and their mind to someone else, they will need some time to rest and remember who they are. While it's so much fun being in a relationship, individuality is precious and refreshing to an introvert and alone time is critical for individuality.
6. Quirky cutie
Introverts usually step to the beat of a different drum and it's fascinating to extroverts and introverts alike to really get to know an introvert. Not only is an introverts personal world fascinating but it's also probably full of quirks and cute things that they're super embarrassed to show. But when they do show you their funny and passionate side it's so much fun to see them light up or turn beet red with embarrassment and you can't help but laugh because someone who seems so aloof is really just a little weirdo just like you.
7. Support
They're usually there for you 25/8 because you're their best friend. Without you, they'd probably be off in their own world socializing only once in a blue moon so when you (their best friend) need them, they'll drop their world for your needs. You're their special person and your needs become almost as important as their own.
Shoutout to all you introverts out there who are probably reading an article like this instead of hanging out in a group of people. When you find a fellow introvert to date it's a wonderful thing full of comfortable silences, new discoveries and mutual appreciation of alone time.
