Why can my significant other when we are fighting post about things on social media or talk to people about it yet I can't do the same?

Anonymous

Especially here lately when we argue or fight my significant other has taken to posting things on Facebook or other social media directed towards me or about me and talking to people about our situation and about me. Yet at the same time it's not okay for me to do so I can't talk to anybody else about it and I can't make a post that's anywhere near what she thinks might be derogatory without it causing a bigger fight and granted I wouldn't make a post like that in the first place because it's not public knowledge and public business what we do in our relationship. But I can't even talk to family or friends about what's going on cuz if it comes back to her which a lot of the times it does all hell breaks loose. And she is still continuously talking to her ex as well and doesn't see why I make such a big deal out of it and doesn't care that I don't like that she talks to him she made that blatantly clear. She has loaned him money behind my back granted it was her own money but that's not the point. She keeps deleting her messages with him. And I have seen several :-* emojis I have seen him tell her that he loves her and she also allows him to call her babe and baby. Yet we have been together for 6 years. I can always tell when he's coming back around even if I don't see him on the social media platforms. Because we go from having normal relationship couple problems to basically the whole world is falling apart and she has issues with almost everything I do. And last time that I mentioned that it was okay for her to talk to somebody but not me to talk to my friends or something about it she said well I've known my friends for 16 or more years but yet if I go to talk to my friends I've known for that long about it and she finds out about it it's not the same it's a very big double standard just like her talking to her ex I had an ex a few years ago that supposedly was supposedly messaging me and wasn't and was brought out to be a lie but that didn't stop her attitude

She is one of those that will not admit when she's wrong will never say sorry even when proven wrong. I'm the only one with a job outside of the house. She has a little side thing that she does that she was doing before I met her. And we have a legitimate license business together as well so we are not young punk little kids so I don't understand why she's acting like this

She will be just fine one moment and cutting up and acting goofy in the next minute she will be I hate you and you can't do anything right kind of thing. Even went as far as threatening to pack her stuff and leave because she got mad about somebody else getting donations for an organization like hers and saying that I wasn't doing enough because I wasn't getting her organization donations like the other person's organization was getting. Yet I work 109 Plus hours every 2 weeks
