What should I do?

I’ve been hanging out with the guy for months now. At first I was super confused as to what he wanted. He was always sending mixed signals, yet we’d hang out any chance we got. A few weeks ago I noticed he changed a little. I thought it was just me but he mentioned something about it too. He started messaging me more, wanting to hang out more, when we out he would buy things for me. He even mentioned to me that we’re taking it step by step and that we have to have trust to start anything.

This past week he sort of stopped texting as much. I was confused. But then we hung out later in the week and he told me he was busy or just didn’t want to be on his phone. When we hung out this week, he’s always been super affectionate...more than before. He also mentioned something like “you should rethink what you’re getting yourself into” in regards to him (joking obviously). We hung out yesterday really quick before he went to work and after he left he texted me saying he wished we could’ve hung out more and we ended up texting all day. I sent him one snap today and he just opened it and didn’t reply. I don’t wanna make the wrong move and mess this up. But idk how to move forward? I don’t want to seem too clingy but I want to text him!! Help!!!
