Hero ?

What'd I run into? How should I have done this differently on all streets?

My thoughts on flop was I planned to bet this amount anyway, so I bet it as a raise instead. Should i be more wary with minbets? Sometimes its "I'm too weak to bet more" and sometimes its "here fishy fishy fishy"

re-reading this, I'm now wondering what the heck I was doing. Now this feels like a stupid question. So, just a continuation bet turned into a raise and didn't scare him off... next. Or is there a bigger error in here?
