Leo woman and Sag guy - interested or not?

I've only read about Sags. Getting to know one just recently. We've been texting.

I like reserved people to some extent but over time, reserved people become difficult for me to deal with.

Me - frank, straightforward, open, Blunt, fast-paced when interested, lazy/zombie-like when bored.

He's initiated the contact the first time over chat. After that, for a few weeks or even over a month now, I'm the one initiating the chat most of the times. But he responds well. But all his responses seem to be like that of a reserved person. Ask them a favour; they'll do just that. Ask them a question; they'll answer just that.

He's living very close to my place. Those fellows living far away and even those living in neighbouring states have asked me out. But this guy has hardly ever asked anything like that, but still favours and chat happen.

Are you Sag men reserved with Leo women? I remember a Taurean stating that he's free with all other women but he can't be so bold with Leo females. Could that be the case? I don't know. I'm just asking.

The attraction between leos and sags is there but I feel like it doesn't last for too long

something is missing
