i agree. if you believe in fate all the whys to the split don't matter anymore. many of us are in the same boat, they said one thing but didn't follow through. maybe they meant it at the point of time when they said it, but there are other variables too and even if there is no variable, feelings change. and some of us are not even given a reason. but after some time the reason doesn't matter anymore. if they want to live without us, we let them go.
as for why the psychics couldn't see certain events happening, firstly, oh boy i won't dare to expect them to be so powerful. secondly, maybe many things we are not supposed to know beforehand. we cannot play God. If God wants someone to be sick or to die, He has his reasons. who are we to interfere with it? personally i won't call the psychics to ask for extraordinary events, if i do this i will be conditioning myself to be paranoid and not at ease. i will choose God instead of psychics to deal with life events.
