I (24F) need help with figuring out this guy (23M)

Okay so idk how this works but I don’t have very many people in my life I can ask about this subject. So for context this guy and I were together for a little over 4 years. We broke up about a month or so ago and things didn’t end on bad terms at all, so much so that the idea of getting back together is present. Now he knows that I want to get back together. He constantly shows me attention, constantly tells me he loves me, gives me every signal under the sun that he’s open to getting back together but when I directly ask him about getting back together it’s like he shuts down and says “I don’t know” and i genuinely don’t understand. Has anyone else dealt with a similar situation? Like why go out of your way to show me you love me and that you care but then when you’re faced when getting back together you suddenly don’t know what you want?? Am I being played with? Like what’s going on?
