Am I a bad friend?

I’ve been “best friends” with this girl for 2/3 years now. She’s had this bf for about 4/5 years.. she’s been there for me at my worst times but the thing is, it’s so uncomfortable hanging out with them together. They’re constantly arguing, whenever I’ve brought a partner around they’d tell me not to ever take them back because it’s so uncomfortable and just so much negativity. We had got closer this year because our kids are the same age but if I’d go over she wants him RIGHT there with us on the table. Where I just want girl talk.. they’ve been arguing more and more recently and she has been saying she’s done with him blah blah blah but she would use him. He tried to win her back by taking her out and I asked why does she entertain that and she goes “if he wants to pay, why not” I distance myself after that. Or if I invite her out she needs permission from him, I’m so over it. I had reached out to her this past weekend to have girl talk she asked where I said right here by my house (bar) she goes no can we go to like a restaurant. (Because her bf didn’t want her going to the sports bar with me) I just ignored her.

Fast forward she text me asking when can we hangout she misses me and I said okay this upcoming Wednesday she agreed. I wanted to explain why I’ve been the way I’ve been.. she just text me saying of it’s okay if her bf and his friend come.. I’m just over it. Am I wrong???

We can never have girl time and it’s so uncomfortable being around them. AND she always wants him around when we’re hanging out

Please let me know, how do I even approach this

Part of me just wants to give up on this friendship
