He’s your best friend. He cancels hanging out with you frequently. He pretends nothings wrong. He defends his girlfriend when you bring up how she’s changing him. He calls you clingy and annoying. He doesn’t pay attention to you anymore. He doesn’t care about your feelings. He doesn’t answer your texts and calls, he responds to them hours later or days later. He thinks you’re jealous of his relationship for the reason you’re upset with him.
