I need opinions

So the guy that I use to talk to decided to hit me up more often on text and snapchat so he obviously brought up the past about us and he said to me " I remember when you said to me that I will never have you again" obviously I said it out of anger only because he was not there for me when I needed him. So now he came back but my problem with him is he always working like I am and he is always telling me when are you coming to see me and I say the same thing and we never have an answer. Is like our schedule sucks. So today I said lets make an agreement so that way we can spend some time  with each other and he replies with the "idk"... My question for you my ladies is what should I do ? Because he says he wants to see me and he hits me up on the days that I'm working which I cannot go visit him. I'm getting really annoyed 🙄 and I don't know what to do. Should I wait and let things go on its own or should I just let it go?
