Help! I got friends in the blues!

I need some advice to give my friends. They both like the same guy and just today my friend HJ told the guy if she were ETC then she would break up with him for being boring( such as not holding her hand or giving her goodbyes). So know he's avoding ETC( thinking she going to break up with him) and HJ believes its all her fault and  he wont listen to her apologies . I dont know what to do!  They can't be sad on a holiday!

Does any one know what I can do to cheer them up?
