I'm thinking about ghosting my roommate.
Why would you ghost your roommate?
She is not a talkative person and it feels awkward to converse with her. I want to have a roommate who'll be much more fun to hang around.
It sounds like you just haven't gotten to know each other. Roommates are expected to respect one another and work out their differences.
Then I guess I'll ghost her after all.
That's not what I'm saying. I think you should try and get to know her a little better.
