Dating

So I’ve been talking to this guy for about 3 months, going on multiple dates atleast once a week and hes generally fun to hang out with(still haven’t talked about exclusivity yet🙄). but One red flag ive noticed is that I don’t like how inconsiderate he can be. Hes been late to pick me up on dates on multiple occasions, twice where we missed a movie and my last straw was when he was an hour late to pick me up to play tennis. He texted me saying “hes on his way” and didn’t acknowledge that he was late or anything while i sat there worried about him. I told him to forget it and not to come. He said he got caught up helping a friend but it bothered me that he didn’t say anything before or after the fact. Am i looking to much into it? I told him how i felt and he said he would work on it but now he hasn’t talked to me in two days. Should i just block him and move on?
