Do you think I should be mad at my ex?

Basically ongoing situationship for 2 years. We knew each other really well in person. He broke my heart big time repeatedly. Finally he wanted to make a go of things and re-followed me on social media. We started texting properly but he was being dry then out of nowhere he just blocked me. I found out that it was because my brother warned him to leave me alone & quit playing with me. I feel like he could have had the decency to speak to me first though but just flat out blocked/ghosted me. 
Then last week he went by my house and was staring in. 
Opinions?
