My bestfriend's online bf dumped her with just a msg saying his parents dont approve of her.?

the bullshit thing is his parents have never met her nor even spoken 2 her.This guy has also not met her but has seen her pic only.but he had made promises of marrying her and said that he loved her 4 last 7 months.and then today morning he spoke to her very lovingly.and just 3 hours later he msgs her and says that he cant be bf anymore,its better if they are just friends.when she caled him he said his parents said no to the relationship so he is breaking and said that they can be friends.It was my bestfriend's first love.She is heartbroken.I dont know what to say or do for her.M also dealing with a heartbreak but m doing it alone as she is not matured enough to understand what I am going through.But all my life I have handled my relationships and breakups with no help.So now I dont know what should I do?AND WHAT SHOULD SHE DO?SHE IS LOOKING UP TO ME TO TELL HER WHAT TO DO NEXT.BUT M CONFUSED MYSELF.HELP ME
