PLEASE HELP!!!! (Advice)

I really need some advice on a Sagittarius guy...I'm currently talking to this guy and I know we aren't a couple and maybe it's just me but I'm trying not to get too close. He and I both work and I also go to college but he and I have only hung out a handful of times. He claims me as his in public when people ask and he treats me very well but he's so fluttery (but sometimes distant)... maybe it's just me I'm very confused on many levels does he want me or doesn't he? 😞
