Recently, I suggested going to an event with a guy I'm interested in that we both were planning on going to anyway(it came up in conversation). He messaged me later that night and said to text in the morning to figure out meeting up. I met up with him and his friend (he mentioned when I said about going that his friend was going too). The day ended up being really fun; we all got along pretty well and it didn't feel awkward or anything. Then during the week, he messaged me about hanging out on Saturday. I had already made plans so I suggested Sunday instead. This time it was just the two of us and we hung out for awhile. Afterwards, he said that he was going to be busy on the weekend but that if I was doing anything during the week to message him. I wanted to get other people's perspectives on how to take that.
Is he being "lazy" by telling me to take initiative? Which I don't mind, but I don't want to be the only one either; I want to know he's interested in me enough to contact me first and not wait for me to contact him. Is he thinking that it's my turn to ask (he messaged first about the weekend, so he did take the initiative; I only offered an alternative suggestion because I couldn't go then)? I guess the other part of this is if he's interested in me as friends or possibly to date (and right now just getting to know me better)? I suppose if I do end up messaging him this week, then I would wait for him to figure out something to do the next time so it's not always me making plans/suggesting things (again I want to know he wants to spend time with me).
