I sure wish I was good at friendships. I tend to pull away from friends after a conflict and that’s not the best thing. I’ve lost good friends due to either not speaking up soon enough or pulling away abruptly when I’m fed up. I think once you cool down it’s a great idea to reach out and apologize. It might be a few days or weeks until your friend reciprocates but maybe she will just need some space. I think if the friendship is a good one then it’s worth keeping the connection.
