Breakup

A female friend ( would call her A) was dating this gir (would call her h). A was inlove with this H and even though they became official, and A was already inlove with H, H only said I love you aftrt they became official and let A know she is not inlove with her but loves her. Well after being official for less than 2 months H broke up with A saying A is perfect and does everything right but H is not inlove and also doesnt have feelings for A anymore as H used to have feelings for A but was not inlove. A is devasted and doesnt know how to move on. Im not sure how to help A move on. Any advice please. A begged so much for H to give a chance to see if A can make things different but H said no. A immediately blocked H everywhere just to find a way not to see H on any social media. Any advice for A?
