Is it alarming to have a new boyfriend a month after a 5 year relationship?

My best friend broken up with her boyfriend of 5 years bc he moved countries with his fam and he treated her poorly anyway so waiting for him to come back in a year felt pointless …

A month and a half later she has a whole new boyfriend …. But it’s alarming to me because she was literally just talking about getting flights to visit him 3 weeks ago now she’s in a new relationship
