Am i the asshole for wanting my best friend to break up with her boyfriend?

My best friend has been dating her boyfriend for about 6 months, and I’ve started to notice some red flags that make me feel like their relationship is really unhealthy. I don’t know if I’d be the asshole for wanting them to break up, but here’s why I feel this way:

Whenever I’m around them, their relationship seems really unstable. They constantly fight over the smallest things, and it’s exhausting to witness. My best friend often tells me she wants to break up with him and even says she’s starting to hate him. She’s said more than once that he’s driving her crazy.

On top of that, he’s called her names like “bitch,” and even went on her Snapchat to block her guy best friend. Meanwhile, she has never cheated and never would — so I don’t see why he feels the need to control who she talks to.

She jokes about their fights, but I can tell it’s taking a toll on her. From the outside, it just looks toxic, and I feel like she deserves way better. But I’m not sure if I’d be overstepping by trying to push her to end things.

So, would I be the asshole for wanting to break them up?
