friends starting to date suck

my highschool friend started to date this girl I'm the middle of the year and she would dump us to spend time with her, at that time I was like alr u to girl cus yeah, they're fresh dating, makes sense they'd jump in any free time to cuddle and kiss, it's fair! but, like, the girl she's dating graduated so now she'll be alone and probs going to come back to us and idk how I feel about that, she's been ranting in twitter saying we pushed her away and yada yada but whenever we plan hangouts she's always ditching cus she's with her girl. I feel a little bad cus I really appreciate her friendship and idk, wish she tried harder to balance relationship with friendship
