Could my gem be true?

Im a sag and I just started dating this gem, for about a month, we are friends/lovers, but not official yet, he says he likes me alot, but yet I have doubts if he could ever really be sincere. I really care for him alot, and we see each other like every other day, and he says Im the nicest girl he has met, so how can I keep him interested in me long term? I want this to work out but I've heard that gems are hard to keep.

I've only semi-dated a Gem and I think the best way to keep them is to let them have their freedom and show that you enjoy yours as well. I don't think they like to be emotionally stifled or anything, so don't be in any way clingy. I've noticed that they can be quite sincere when they want to be but thrive off playing games as well. Like the guy I was seeing would like test me to see how much I liked him, and when I'd say I had another date he'd be TOO ok with it all, if you know what I mean. and then text me all weekend to see what I was doing. They're really charmering though and the best sign to flirt with I think, always up for banter! And I s'pose that's what keeps us interested!

ok i'm a gemini female....and i have alot of gem guy friends...Yes they like to have there fun but if they really really like you, it's all about you..Make him chase you alittle bit and be playful ..of course be yourself but thats always a plus...Tease him..Give him things to make him think and figure out..He's all about the mind before anything else..If you got that going he'll love ya 😉 but becareful bc our words are our weapons..... if you need anything else let me know , i'd love to help ya =)

Thanks for your replies, I will take in everything that was said.
