Search Results: celebrating birthdays

I always knew my crush and I were different. He's the "cool guy" who never smiles and isn't afraid to express himself (even if it's hurtful). I'm the naturally playful and flirty type. My guy friends always tell me that when they first met me they thought I was cool, cold and distant but now they see how clumsy and flirty I really am.
Today, I've been texting with my crush, and immediately we could see how different we are. In just a day, I've learned: he doesn't like parties (I'm all about the life of the party - probably because I'm a musician), doesn't like celebrating his birthday (I always celebrate my birthday with friends) and that he hates summer (Summer is my favorite season).
The only thing I see that we have in common so far is that we're dog people who care about the environment. Is that enough to have in common with a partner? There aren't any mutual activities we do or hobbies.
He's a PHD in Science and I'm an Ethics undergrad, French minor.
I'm multilungual, he just speaks English.
I'm a Pisces, he's a Taurus.
I spend my free time singing, dancing, going out with friends, shopping, reading, or watching Criminal Minds, Roswell and K-Drama. He spends his free time gardening, tutoring and who knows? Probably watching Nat Geo and Ted Talks with his dog and a few cans of beer.
He's totally a beer person. I'm a cocktail person.
Till today, I didn't really have any doubts about pursuing him because I've been so blinded by him, but now I'm slightly worried that even if we end up together it wouldn't work out because we're so different. I mean, what would we even do together other than have sex? 😏😏
I've never pursued someone who's this different from me.
Should I be worried, or not? Do opposites really attract? Have you ever pursued/dated someone who was really different from you?

Is celebrating your birthday overrated?
