(Ex?) best friend

My best friend recently got a boyfriend and she’s absolutely in love, she won’t talk about anything else but him.

The thing is I’m absolutely sick of it and I (politely) told her to chill a little bit, but instead she told me that I was jealous of her because I’ve never had a boyfriend, and she came up with her parents divorce (I absolutely hate when she does that...like she’s the only child with divorced parents) and told me she had a hard time with her parents’ divorce so I couldn’t be mad at her (they divorced before she was born). At the end I apologized (for doing nothing apparently) and tried to restore our friendship but she’s been so Fcking childish...like she talks crap about people just because they’re talking to me...should I just tell her to fuck off? I really don’t want to end our friendship but she’s really pissing me off
