Curious about past crush

Hi,

Though I have different boyfriend who I am compatible with, I sometimes get curious about an past crush who I was wild about for years. Though this crush and I are not compatible and he's a jerk who didn't like my back, I started wondering about how he was doing and decided to look at his YT video channel. When I looked while signed into my account, I discovered that he blocked me, though I have not really talked to him in over 8 years. The reason I was curious is because he has has a history of jerking me around and sometimes he's been interested, however, he's had a history of gaslighting and giving me the silent treatment. So, I decided to block him from all my social media and other means of contacts.
