Friendships

My bestfriend just told me that whenever I’m in a relationship with someone I put her second. But I don’t. I put her before ANYONE in my life. And it upsets me so much that she even says that. Sometimes I am on a call with a bf or whatever and I’ll decline her call because it’ll be rude to just leave. But Idk. She has a bf at the moment and says she’s treating us equally I guess but in my opinion I wish she could just put her bestfriend first too. I’m just so stressed about so many things and this is making it worse.
