Does my closest friend hate me? What did I do wrong?

it feels like me and my close friend aren't friends anymore. They is leaving me out and not telling me stuff but they would tell our other friends. They’re rude to me and makes fun of me in front of our other friends. They have this other friend in our friend group and they act like their siblings or best friends. They disrespects me a lot and when they get home they call me and acts like what they said never happened. Sometimes says rude jokes about my family i know it’s a joke but it’s just disrespectful. What did i actually do i’ve done nothing but support them and try and guide them to living a better lifestyle. I haven’t forced them to do anything. maybe i’m being to nice? i’ve felt like this for a long time
