ugh help

so I'm not jealous and I'm really happy that my bestfriend has a new boyfriend just I'm getting really annoyed. All she does is talk to him non stop. When we're hanging out we might as well not be because it's like she's not even here. and all she does is talk about him and send me their messages. honestly just want to be like "I don't care" but she's the type that'd get probably get mad. and she was saying how when I get a boyfriend I'll do the same and I told her no that's not how I am, I know how to separate friend time and boyfriend time. I don't know, I can't really say nothing without shit turning into a fightttt! ughhhh hellppp
