Why would a guy go a month without contacting you?

So I’ve asked about this dude before. He’s driving me crazy. So long story short, I asked a guy out on a date. He said yes. I thought the date was awesome. 2 weeks later he hadnt asked me on a second. So I decided to ask him again. He takes a week to reply and says yes. But by the time he replied, I already had made plans. I got so fed up with it that I said “oh maybe another time” and decided to move on. He said he would let me know when he’s free.

So a month goes by and I don’t hear from him, and then out of no where he texts me asking for another date?!

He obviously sucks at communicating. And now that he asked me on another date I’m sucked back into the whole cycle!

Now I know you probably think I should just say no, but hear me out. Either he called me up again for an ego boost. If that’s the case, I definitely don’t want to feed his ego. Or maybe he is interested, or wants to try again? He does own his own business and goes to school so I can understand how he would be super busy.

Should I go on the second date but go in without expecting anything from it? What do you all think? Or am I overreacting?
