Search Results: talking to a girl on the internet

I met this girl on the internet (let's call her "S"), she's sweet, kind and apparently an introvert. we live in a different country but we've been talking through social media for about a year now.

lately S seemed a bit off, when I asked her about it she said that her friend acted like a bitch (like left her alone in the club every 15 minutes, always trying to control her and just seems pissed off everytime S talked about her and the last trigger was bailing out on S from a concert they're planning to attend) they had a serious argument and now S is on no speaking terms with her.

when I asked S if she's her bff she said no (but I know better, S hung a lot with her and basically inseparable since high school) and S said that she's better off without her.

two days ago, S said that she'll travel solo to Bulgaria (she's a Dutch) for two weeks to escape and be independent. this makes me worried about S well being in Bulgaria (she's alone) and also worried about her social life in her town because S is an introvert and her inseparable best friend won't speak to her and I think S is depressed about it so that's why S chose to escape her little town for a while.

I wanted to help S by messaging her best friend and persuade her to put all of these things behind and be friend with S again but I'm afraid S will hate me for interfering with her social life and I never talked to S' best friend, so we are basically strangers.

so what should I do girls/guys?
