trying not to be clingy but show an interest

there is this guy who i met that i have really started to like and i want to show that i have an interest in him without being too clingy but i also don’t want to seem like i’m being distant and uninterested in him. we met on tinder actually and hit it off pretty early on. i wasn’t planning on it going anywhere just because of the nature that we met. but he was pretty persistent in talking to me even after i left him on open for several days before we really started talking. he asked me to add him on snap and i didn’t and then he asked again so i did. and we started to get to know each other more and have gone out 2 times and i’m really starting to fall for him. he and i are both in college and he’s 2 years older than me which means he is legally able to drink which isn’t an issue other than he might have more in common with older girls than myself. basically, i need some advice on what i should do in order to show that i am interested but not clingy but also not be too distant so that he thinks i’m uninterested. i’ve never really been in this situation before and don’t really know what to do.

side note** he did say the last time that we hung out that he wanted to see me again but i wasn’t sure if that was just him being nice. he is a very very sweet guy and is genuine so i do think that he has an interest in me too. i just don’t want to seem overbearing. please help, anything is appreciated
