My thoughts are as follows......"You're sanity and self respect would be severely compromised by going on this trip......in addition, your friend is trying her best to "mask" the problems in her marriage and you would be an enabler to contribute....Seeker...clearly, you are a woman motivated by higher creative/self examined powers) and I hope that you don't give in to the "bait" being dangled before you....they need to work this respect issue out between the two of them before they can be legitimate friends w/anyone......hang tough...grace
