Guy's Behavior

Was it bound to happen? Should I act cool if he reaches out?

To make a long story short. We'd been talking online for a few months. At first we were just having fun but eventually he started catching feelings and I kinda liked him as well. We both knew that things weren't gonna go anywhere due to where we were in life & being long distance. So we tried blocking each other & stopping contact a few times but we never succeeded at that for long. We decided to just keeping having our little fun but not talk otp as much or text as much. And things seemed to be going well & fun. Except he suddenly stopped coming online & it's been 3 weeks now... I don't know if he ghosted me, or something went wrong since he did mention he was having covid like symptoms last time we spoke. But unless something went terribly wrong I think that he's ghosted me... I'm upset that he'd just ghost me, but I also feel like it'd be unfair of me to ask for more of him... since things really weren't moving forward because of me. And we did have those conversations but they never worked. So maybe he just decided this was the move.
