My crush took 1 week to reply. should I even bother replying him back?

My crush has been texting with me for months now and he always continues the convo on by asking questions and so I did the same. Sometimes he would reply quickly then the latest was like 2 days. However this time he left me on seen for a week to reply!!! When he replied he never apologised for replying this late. I just feel like it’s so disrespectful in general. Honestly it’s such a big turn off. Should I be petty and just not reply to him ever? Or do you think I should reply? Cause I don’t want to make it too obvious that it got to me by removing him off my close friends and everything but o really don’t want to continue talking with him anymore. It’s pissing me off. What do you guys think? Should I just ghost him forever at this point? Or is that too childish of me?
