Ex Wants to Meet up Then Changes his Mind?

What is your take on this?

My ex and I have been broken up for about four months. Recently, he just started contacting me again. So we were Skype chatting last night, and he brought up the idea to meet up. Now I was quite surprised, because when we were together, it was long distance, and he lives 2.5 hours away from me. I asked him why, and his reasoning was that he "just thought to do it" and "it just came" to him. :/ So I proposed to meet him halfway. It was just so random, because he suggested going to the shooting range, which I've never done before. He told me how much the ammo costs (he wanted me to pitch in,) but after Christmas, I'm pretty much low on cash, and I don't have twenty dollars to be spending on rounds. Then I said I was going shopping today (I received a ton of gift cards,) so he said that was cool, and that's what we agreed on. He made a comment that he was supposed to come up with this idea and that I in turn should've turned him down, which would make me look like a "meanie", whatever that means.

So! I texted him this morning to see if we were still on, and he just said "no". Now honestly, I don't really care that he said "no", I just want to see if anyone out there understands why he would want to meet me then change his mind!
