The situation I was in wasn't with BP but with Asperger's & I understand the hurt that finally adds up so bad over the 33 years I lived with it that when I finally left it was such a relief & I found out what even alone & away was happier than trapped & married.

Sometimes the hurts do build up so bad that nothing can fix the final feeling we are left with even when change & meds can fix the wrongs. I know personally my belief is that marriage is a life long commitment for better or worse but I know from personal experience that there comes a time when for our own mental wellness we need to end the relationship however sad that may be & however much it goes against that life long commitment.
