Biechy thing to say on FB?

[eagerpig506]

A fb acquaintance wrote this, and I'm pretty sure she meant this toward me!

"Females in a relationship, who flirt with any other male except for their bf, of course he is going to leave. Even if you don't act on your firtatious advances, even if you don't mean anything by it, it still hurts him. It makes him feel like you don't need only attention from him, you just want male attention from anybody and only his isn't good enough."

Then she continues to write a comment below:

"It is time to grow up and stop trying so hard. If you are mature enough for a real relationship, you are mature enough to put all your eggs in one basket. I am happy to say I don't feel the need to flirt. Ryan makes me feel beautiful and that is all I need in this world is only his attention :-)"

Do you think she is rude for saying this on her fb?
