Why does my sister treat every boyfriend I have like they are hers but doesn’t want me knowing anyone she dates?

I’m really close to my sister and I trusted her until I found out about her weird ways. I have had a few boyfriends not a lot but she has met every single one of them. I’ve never met any of her boyfriend and he doesn’t like me coming near him. She doesn’t tell me any of her business but I tell her mine. I mean no business to where There’s was this I ne boyfriend I had that she would hang out with but would deny it when I asked about it.

She treats my boyfriends like they are hers too. Even when they aren’t type.

She used to live with an ex boyfriend and her phone was acting up so she texted me on his. So I texted back another day asking for a Certain picture of her thinking I was talking to her and it was him and he sends a picture of himself. I tell her and she gets mad at me instead of him and tells me she doesn’t remember texting me on his phone at all. She literally almost fought me.
