The question "what would it do" makes me think that perhaps you're trying to manipulate her. Making her miss you by going dark is one thing, being unavailable when she needs to discuss real issues is another.
Whether you want to help her out is entirely up to you. If you don't want to help her because it's inconvenient, that's fair. If it is no inconvenience and you're just holding out because you want to teach her a lesson, then it's just pettiness.
