Search Results: talking to an old friend

I recently reconnected with an old acquaintance through tinder (we had met a few times before because we had mutual friends). We matched about a week ago and have been talking since. At first, I thought we were just going to have a short conversation, and then let things die out, but things actually progressed and we went from talking on tinder to talking on Instagram and went from texting to sending voice messages, which I thought was a good sign because if he didn't want to talk to me I don't think he would do that (he even went as far as sending me a picture of his face saying good morning a few days ago). I'm just saying this so you understand that this isn't a situation where he's being dry and I'm just not taking the hint. Here's the thing, he usually takes a few hours to text back, but today he hasn't texted back at all (last I sent him was a voice message this morning responding to something he had told me last night after I had gone to bed). I didn't really think much of it, just thought he might be busy, until an hour ago, that I got on Instagram and realized he had posed a story on his profile, but still hasn’t texted me back so I don’t know how I should take that.
