when is enough, enough???

this one is about my friend.  i am not supposed to be talking about it, let alone write it but i cant get her out of my mind since she dropped by two days ago.  i think i scolded her bad and i feel guilty.  maybe that's why i am writing this, to get someone else's opinion.  not necessarily an ally.

the story is, she is a she and is in-love with another she.  actually they have been living together already for more than a decade.  sounds like a strong relationship?  only on the surface if you ask me.  the girl betrayed her for i dont know how many times already.  the worse is, she even sired a baby whom my friend is devotedly taking care of since.  okay, okay...  so everyone is entitle to commit mistake.  she was wrong and she was forgiven.  end of the story.  so why am i still reacting?  because here she goes again telling my friend she wants out as she is yet again in-love with someone else.  i dont say i blame her.  it may have taken a while but she still realized she is a normal human being, capable falling in love with the opposite sex, which is just the normal thing in the first place.  that's why i am not mad at her one bit.  i am at my friend, because she would not let her go. 

i asked her where does she think she stands now and she said in limbo....  i said why not face it head on?  she got a thousand and one excuses which really pissed me off.  in the end, after the not so good exchanged of not so nice words, i simply told her she is selfish.  i know i was harsh but i was hoping that would open her mind.  it did not :-(  when is she going to wake up?  will she ever grow up?  when she will realize that enough is enough?
