Crush confusing me

Ok i just need to make sure I’m now over thinking this so I’m just gonna try to make this as short as I can. I have a crush and I decided to try and text him simply (Hey are you) unfortunately it didn’t work, he blocked. Then like a 2-3weeks not really sure but he unblocked me. Then just now like earlier today he made his Instagram public (it was private). He also has a gf I believe (I found that out at homecoming) So I guess I’m asking is am I overthinking this all? Advice would be appreciated thanks! I’m just super confused.
