He seems uninterested after sex. HELP?

I started talking to this guy about two weeks ago and things have been going really great. we would have a great talks and text throughout the day but ever since we had sex on Sunday it’s been kind of like I’ve been looking for that attention that he was giving me before. I will say that in the two weeks we were talking nonstop he would stay up a little too late saying things like “if I don’t stay up with you someone else will” and he was late for work twice in those two weeks so he said that he’s trying to get his sleep schedule back together so I’m trying to be more mindful of that, but pretty much every day this week our chatting has been pretty sparse and there’s only been one phone call when we used to talk on the phone and FaceTime like every day. I get really anxious when things start going this way because I’m used to getting ghosted and having people tell me im TOO much and I get that. So on Wednesday I blocked him from all my social media just because I was feeling like he was going to ghost me so I wanted to do it first. I deleted his number so I couldn’t bother him anymore and He ended up calling me asking me what was wrong. I let him know and he told me that he isn’t ignoring me. He’s just busy at work, and last night (Friday night) I kinda got upset with him because he was just leaving my messages on read and not responding to them. He told me he’d talk to me in the morning that he was just getting ready for bed and he’s not ignoring me. So in this week, he hasn’t talked to me as much but has repeatedly assured me that he’s not ignoring me. Should I just take that as he’s not ignoring me or trying to let me down easy or am I just being a crazy person.

Also I feel like I’m fucking this up even if he is still interested in me. I need allll the advice please help!
