Sagittarius and Gemini Compatability

Can anyone give me some insight on the compatibility between me and this gemini I just met? I really don't know any geminis so any input would help. Thanks!

Me:

hehe I've this sag friend and I don't know his full chart (and I don't think I'd bother to find out later..because we get along just fine lol)

we get along well as I just wrote above.. we have good conversations.. we both love talking about and doing exciting things, activities.. have very clear communication.. both are direct, upfront, so there's no obscurity as in what is her/his intention..? is there some meaning behind this or that s/he said? .. we just ask each other and we get our answers..
seems my sag friend is always very positive.. and as a gem I seem to have to some mood swings.. some call it being capricious.. so sometimes I don't get how my sag friend can stay ever be happy state lol but that works out good for us in the end.. even if I become a bit cranky, being capricious, he just d'awww! awwww! you'll be fine! and carries on.. (and this, he is right lol because I soon bounce back no matter how shitty I feel at one moment.. but just at that moment, I tend to rant a bit lol) but still gives out good, practical advice when I ask him of it.. without being too intense or indirect.. just outright fact, nothing more or less.. and I appreciate the clarity..

we have gone out dates a few times.. had an excellent time.. but weirdly we both agreed that we'd be better remain friends.. it's good that nothing really has changed since then.. we talk about things we like and check out things we're both interested.. I think the reason why this is possible that we are both playful.. and being able to playful is one important factor of a friendship.. so we dated but slipped into friendship very smoothly lol.. talked things out, nothing's left unsaid or unstudied, every stone is turned up etc. this, I say, clear communication.. so now we're happy with our decision.. I just didn't feel myself much attracted to him romantically, so I said so to him and he said he felt the same lol..that we just felt more like friends..

I don't know if this helps, but I have drawn lots of sag men so far, not just this sag friend of mine I have just spoken of.. seems there's some attraction between these two signs.. generally speaking of course..🙂

Thank you xxixxi, we do have really great conversation. He just seems to be way more stubborn than I am and always has to "win" in a conversation. I also have already noticed the mood swings. He gets upset about something really fast but if you mention that he's acting this way he then gets defensive.

But i really like our communication and he can be really affectionate. I didn't think this was the trait of an air sign but I like it.
