Search Results: friends act around girlfriend

So my friend has been dating hi girlfriend for over two years they're both 19 and started dating at 16-17, at first she was super shy, nice and caring and not really causing any issues, he was always angry, jealous and protective but she stayed with him, they broke up and got back together few times and he was always the one calling to apologize.

a little after their first year he started asking me for advice more often (since i give great ones and he admits) and i directed him in the right path, he stopped being super jealous, started being calmer and think more before talking, but he still reminded her every minute how much he loves her and they send texts non stop throught the day and call mutliple times daily.

starting few months ago she started acting weird (around the time she got a new job in a clothes store) she would act btchy, have an atitude, tell him she is free to do whatever she wants and he is not important and doesn't get to decide anything, forbids him from going anywhere where she suspects a girl might like him, whenever he says somethign she doesn't like she would get mad and act in a bitchy way and tell him to not talk to her again, basically she is acting like he's unimportant, has no say in her life and should just say yes without asking why.

Me personally , i suspect she wants to actually break up for real and find another dude who's got an education and a degree, and i also think her friends and giving her all sorts of bad advices (my friend works as mechanic) , so what do you think?
