I broke up with my boyfriend of 6 years over text. Am I an asshole?

I did it to avoid confrontation (our fights used to get very volatile and explosive)

The text message was lengthy and i explained everything I had to in it

But he said after being together for so long, I at least owned him the dignity of saying it to his face.

Should I feel bad?
