Meh. So you are envious of her and it makes you miserable to have her as a Fb friend. And you unfriended her. Hardly the end of the world. I unfriended a woman who I grew up with...a 45 year old friendship. Our political differences were clearly beyond repair. I don't regret my decision. I don't think you need to regret yours. You were unhappy with the friendship, so you took care of yourself and your feelings. Kudos!
