Bachelor Pad 2: Was Holly Durst's engagement announcement to Blake Julian on TV a total bitch move?

Apparently Michael and Holly were engaged and she broke off their engagement last November, then they got back together but shortly afterwards Michael ended the relationship.  They both went on to star in the second season of Bachelor Pad, along with Blake Julian.  

Over the summer we witnessed Michael deciding he was still in love with Holly but we also witnessed Holly flirting with Blake.  One of my many issues with this season of BP was watching Holly pretend she was all broken up about Michael and she was not sure what guy she wanted, Michael or Blake.  For me the choice was obvious, Michael.  

The whole season Blake was a total douche.  He lead Melissa Schreiber on (yes, I realize Melissa is crazy but you just don't treat any girl like that) while moving in on Holly.  But what pisses me off the most is that Blake proposes to Holly a few days before the last episode was filmed and Holly says yes and does not tell Michael.  So Michael finds out that his ex-fiance of less than a year is engaged to another guy on national television.  What a bitch move by Holly.  Holly's reasoning for not telling Michael is that she could not get a hold of him.  

Really?  What a bunch of s**t!  Let's say we believe she could not get a hold of Michael beforehand, Blake did not have to propose and/or Holly did not have to announce the engagement on national television.  Obviously Blake and Holly are selfish fame whores.  That's my opinion on the situation, what is yours?  Was Holly Durst's engagement announcement a total bitch move?
