I agree that it sucks but what everyone said is correct, she is probably hoping you will contact her. I would encourage you to explore why you walked out, maybe reach out to her to let her know you are ok, and maybe even look at past relationships and see if this is something that has replayed before. I’ve done the walking out, quitting with no contact thing, and always ended up going back. I have this run away so you can chase me and show me you care thing though and it has taken me a long time to get to the point where I realize that I don’t need to do that and others can care without chasing after me.
