Am I a bad friend for thinking my friend is the toxic one in her relationship?

Now before you all attack me, know I have talked to my friend about her behavior, thoughts and actions that I find concerning in hopes she’d see it was wrong and change. But I’ve never gone out to tell her shes toxic and Tbh I feel bad thinking this, and thinking her current ex Bf whos she’s trying to work things out with would be better off without her. And she without him.

Her (ex) boyfriend and her dated for about four months before they broke up. She broke up with him. During their relationship she would constantly cause arguments that had already been settled. She’d question his sleeping schedule to the point he had to send her his Apple Watch heart monitor thingy(honestly don’t know what it’s called I don’t own one but it showed his resting heart rate for when she claimed he wasn’t asleep). They are long distance so I guess I understand why she’d be anxious.

She didn’t trust anything he said and he’d always reassure her, show her proof, anything but it never did anything. Finally he stopped being so loving and caring with her. He expressed to her he was tired of always having to justify things and always fighting (she showed me screenshots of their convo). Soon after they broke up and within 24hours she wanted him back but he said no. He wanted space from her because she didn’t know what she wanted or how to trust him.

But she was very persistent. She did not give him space at all... she’d spam him, she’d want to talk about them even though he told her he didn’t want to discuss their relationship and he would be okay with being friends if she still gave him space. (They have a lot of close friends in common)

She began to monitor who he followed, she asked me and multiple friends to follow the new people he followed and even went on to msg girls he followed with a secret account asking them if they were talking to anyone. Trying to see if they’d name him. She also mentioned to him how she noticed he followed some questionable people that seemed like bots and got really mad when he said he didn’t care they were just random accounts.

She would again start arguments and spam him, only stopped when he threatened to block her. And even then it got to that point. He blocked her on everything except Instagram and somehow that made her think they weren’t over cause if he didn’t block her there then he wasn’t done.

I told her it was unhealthy for her to push so hard. To Monitor his following, msg the girls and start conversations about things he didn’t want to discuss. At one point she tried to trick him into coming back to her by lying about going to therapy which she hadn’t even tried to go to at all. She said she would only if he took her back.

After about 5 months she finally got the idea and stopped chasing him and monitoring his things. She finally began to

Give him space. Now he’s talking to her again but she’s starting to act the same all over again, starting arguments and making everything about herself... even when he tells her he’s stressed about work she tells him his mood is making her anxious and makes her feel unwanted. She gets mad when he’s dry but doesn’t even ask if he’s okay. She also hold his past against him. He’s had previous girlfriends ofc but none she knows personally or overlaps with... she gets jealous and anxious about his past but those girls aren’t even in his life anymore.

I’ve tried telling her that she can’t just expect things to be different if she doesn’t change and be better. She constantly tests him too to see if he cares about her.

Honestly he’s an okay guy, he made mistakes too but my friend is too controlling and self centered at times. I know it’s not my relationship and I’m not judging it, or maybe in a way I am but she doesn’t see her actions at all. I don’t think he’s too good for her but I think she just isn’t well for a relationship.... she was this way with her previous ex as well.

I’ve also begun distancing myself from her bc she can be too negative about things at times. I was never close to her up until this last year I took a chance to open up to her but we just handle things very differently im more passive Than she is about things.

Avocado scare?!
