He wants to see me but doesn’t text

So I’ve been going on dates with this guy a bit over a month now. He & I get along splendidly & we laugh all the time we are together. Overall he’s got his shit together, he’s in med-school & his values align with mine. Except the all familiar issue- texting. He will not reply for hours at a time, sometimes with 24hr windows in between. I legitimately reached out to him about this issue , essentially saying “hey it seems like you really aren’t interested in pursuing this relationship, that’s fine if you aren’t just please let me know”. To which he had a long response of saying no he’s most definitely interested he just dislikes texting etc. I honestly aint got a clue what to believe or feel. Maybe I’m needy, sure- but when does it go from “you’re being needy” to “nah he’s not showing interest” ?
