Things were going well until he blocked me on Snapchat

I was friends with this guy on Reddit. We started talking a lot. Then we became friends on *** last Wednesday for more consistent conversations and from there fwb since I didn't want commitment. Things were going great. Up until Saturday. We have different time zones and I panicked as to why he didn't respond to me. Turns out he had work. Which made since because at 3:00 pm for me which was his wake up time,assuming he went to work around 4 pm then got home around 12:46 on my time it made since considering he worked an 8 hour full time job. But the next day Sunday was no different. He said he would be busy until next Friday. Monday due to my PTSD and fear of being ghosted I logged out of *** and took the day off for myself. Tuesday came,I checked my message which was in response to asking him if we'll have any time to talk. He basically said no. So then I responded with I think we should just be friends without the benefits because even though I know you're not ghosting me your inconsistency in messaging is stressing me out. Wednesday morning when I checked again he said he was really sorry and that he didn't intend for this. I said it was okay and it wasn't his fault that I have PTSD from fear of being ghosted and that I want us to still be friends because I care about him. But then I think I said something like "but we can't have this connection anymore". I don't know because it wouldn't let me see the messages. He might have taken this as a misunderstanding, if I did say that, as I want nothing to do with him. Thursday morning,today when I went to go check to see his response he blocked me. We're still friends on Reddit,I assume he forgot to block me on there too. I don't know if I should ask him if it was a misunderstanding or get back at him for hurting me by blocking him on there. I feel like it's my fault for poor choice of wording if that's what I said and I don't know if he did it as a way to "protect me" or out of anger. I cried about it,just cried about it again recently. I feel so confused and hurt. I really liked his personality and even though we couldn't be fwb due to my stress and PTSD I still wanted him in my life even if that meant just friends. Sorry I know this was a rant. I need help.
