Me and my friend have encountered a rough spot. She has way different beliefs than me and I like to bug her a lot when we are talking. She says stuff like 'I'm done' then doesn't answer the messages I send her?
When you "bug" someone, they are certainly going to get upset about it after a while. I don't blame her. Try being nice and forget about your belief differences and be her friend! Then maybe she will return your messages.
