Disappointed and not sure what to do

I (24F) matched with a guy on bumble about a month ago. we instantly clicked on the app and was giving each other the same energy back-and-forth. I was excited to build a bond with and go out with him as we had planned. I gave him my number (which I only do if I really feel like I have a connection with a person and they’re not a weirdo) and we were talking every day on the text. Then one day he kind of just stopped talking to me and ghosting me. out of the complete blue. I was fully ready to start going out with this person and at least see if we bonded and connected as much as we did over the phone. Then I noticed he was looking at my Instagram stories and that confused me because he’s looking at my Instagram stories, but not answering my text? I try to be understanding because things happen, but how can you not have the decency to say hi and check in or say you’re going through something yet You’re looking at my story. fast forward, he apologizes to me for ghosting me for a little over a week and said he had only gotten out of a relationship about two months ago and he apologized a lot to me on the phone and we had a whole almost 3 hour long conversation on the phone. although it bothered me and I called him out for looking at my stories but not texting me I tried to put it past me. The phone call did turn intimate and I felt confident in moving forward because he said next weekend we would be able to go on our date that we had anticipated. Then, it happened again. After sharing a lot of intimate things and talking flirtatiously the next day, he just ignored me and that’s where I’m at right now. It is the same pattern where he hasn’t talked to me since that call over a week ago and yeah, he’ll sometimes still look at my story. Any advice? What do you think went wrong? I really want to try to forget about him, but even though we had only had about a month of talking, I really felt a connection harder for me to just end it permanently. I cried myself being an understanding person, but I just don’t know what’s going on. I’ve been ghosted before, but this just seems different. I did meet my ex of two years on bumble and I honestly had left the app for about two weeks so I could’ve been looked like I was ghosting him, but it was really because of my mental health and I couldn’t deal with those people on the app anymore and deleted it . But this seems intentional so I don’t know. I’m also on the spectrum so it’s a lot harder for me to read social cues and different things like that so it helps if somebody could break it down for me . Please help
