Guys, What happened? Is it too late?

Meet on app. Chatted a week. Hit it off well. Phone conversation was just as great. Our conversations were strong and consistent. No pressure. We just shared our everyday lives. We meet in person. It's the same. Vibe was there. Chemistry was there, so much so, he immediately kissed me at hello. I welcomed it. In person, he shared he may not be able to keep up with all I do. I could stand to slow down, so no problem for me. Once home, he reiterated he liked me and that the chemistry was there. He asked if I like him. I was about to agree, but accidentally went to sleep. Woke up, apologized profusely. Explained I was glad to hear because I wasn't sure if he was in to me. My message was long. He took it the wrong way, so we didn't talk for a little bit. Once we talked the next day, confusion was cleared. We were back on consistency. We met later, 2nd time to meet, and we were intimate. Was very comfortable. The experience was mutual. Since we had sex so quick, I asked will you call me tomorrow. His response, will you answer tomorrow. Next day, everything was consistent. About 3 days later, as we got closer to weekend, conversation started falling off. He made no weekend plans with me. Conversation has now become almost nothing. If I text about news or share some life update, he replies. He stopped initiating conversation. 2 or 3 weeks, we hadn't seen each other, i was direct and said, I want to see you again. He responded with a day. Cool. That day, reached out to make the plans, no response. Nothing that whole week. What happened?

We still follow each other on social media. He watches my stories and still likes my posts.

He is my fav I've met from an app. I think about him everyday. I don't believe he was after sex only. Even if he was, he didn't try again.

Any thoughts as to what happened? Why he's engaged in my social media, but not me directly? Is this, he's really not into me? Is it too late to try to reconnect (been about 6 weeks)?
