Am I in the wrong for “ending my friendship” when my friend stopped making an effort?

Anonymous

My best friend of many years recently started replying more and more slowly to my texts. She also blew me off a couple times to hang out with her other group of friends when we barely see each-other.

i asked her if anything was wrong and if I could do anything to fix it, and she said no she’s just busy. She then didn’t invite me to her birthday or wish me happy birthday on mine like she usually does. She went out with her other friends, though. I thought she had ghosted me over those months and was really upset, so I sent her a breakup text saying “I know we’re no longer besties but I’ll always care about you, etc”

She hasn’t replied but has been ignoring me ever since. Am I in the wrong? Did I end the friendship or did she? Because I don’t know if I hurt her but she definitely hurt me. Have I done wrong? Should I apologise?
