Guy's Behavior

Navigating a Complex Reconnection: Misunderstandings and Mixed Signals with an Old Friend - What are his intentions?

A guy I knew from primary school reconnected with me (let's call him John). We have a lot in common, and he frequently "hearts" many of my messages, but he's also inconsistent with texting. As a result, I wasn't sure if he still had the same feelings for me as he did when we were kids.
After a while, I declined an invitation to meet up for drinks with his friends, but I suggested that we could meet one-on-one later, which he declined. Instead, he asked me to come to his party, to which I agreed. I couldn't tell if this guy was treating it as a group date or if it was just friendship, and I was leaning towards thinking that this was friendship since he didn't want to meet up one on one.
I attended his party, but I feel like our relationship deteriorated due to a significant misunderstanding. I found it strange how he asked me if I could get used to his drinking and smoking. I thought to myself, "Why would he ask a friend that?". I don't know how to flirt, but I now realize that I may have unintentionally flirted when I was laughing at his friend's joke and telling him that he's funny. I also found myself laughing even harder at John's jokes later when he was opening his gifts, so maybe that should have fixed it, but who knows.
John also attempted to make me jealous by touching and hugging other girls at the party. He made sexual innuendo towards me and asked me for hugs throughout the party, which I didn't pick up on in the moment. Near the end of the party, John was drunk and requested to come over to my place to play video games, and I kept asking why, but he wouldn't give me a straight answer. I then agreed through text after the party for a meet-up to play games, but I was unsure about it still, and was planning to make it a group thing with my sibling present. He has a temper, and I noticed he was pissed when texting me after I left the party, though I wasn't sure why, and I dismissed it as his being drunk.

The second party I attended was even worse. He and his friend teased me about certain quirks related to autism to the point where it felt like bullying (or maybe I'm just sensitive). Later in this party I believe I unintentionally flirted again because I was acting cute and laughing at his friend's jokes. John then proceeded to exclude me from conversations and future parties and meetups. He even began telling his friends that he hadn't found a girlfriend yet. However, when it was just the two o

However, when it was just the two of us left at his party, he seemed very angry and wanted me to leave. After I appeared quite upset, he shared his future plans to work toward buying his dream house and showed me more photos of his trip.
