Why dose it still hurt..?

So im a wolf therian (F) and recently me and my bf(who isn’t a theiran but supports I am) did “it”(idk if that part is allowed on here) and a few hours after I kept calling him my mate and he told me not to which kinda made me feel rejected and game my heart hurt and i don’t know why it still hurts when he told me it was bc he didn’t like the name and I apologized for crying about it because it’s childish to cry over something like that but I already know it was an overreaction so why dose it still hurt? Why do I still feel rejected? Has anyone else even had this problem? And dose anyone know how to stop it..?
