How to talk to friend about this.

I need advice on how to start a conversation on the phone about how someone feels because how they are treating me hurts and I think maybe they don’t realise but I know if I bring it up via text they won’t reply as they don’t like talking about these things. They’re very important to me but I’m very hurt by how I’ve been treated lately and want to know if I done something wrong.

How do I ask if I done something wrong or begin a conversation about feelings like this without them trying to avoid it?
