It's confusing when someone you love changes. See at some point every one of these people WAS a good person, noone gets into a relationship with someone who is shitty from the start. So your left with that image of the person you fell in love with thinking that person is still there, hes just hiding and maybe if i do the things hes/shes saying then that person will come back. maybe if i get the shit kicked out of me enough times then hell see how much it hurts me and itll stop. it is unfortunate how these people controle and ruin the lives of any and all the people who love them and its very hard to watch that happen and really there are only one or two real solutions. See my normal awnser, beating the shit out of the person to within an inch of there lives and then beating them just a little more, its a short term solution because no matter what you cant be around all the time and you cant protect that person forever, also in reality that person is just going to take out its new feelings of anger and resentment of getting there as kicked by a stronger and better man/woman on said person to make them feel powerful, manly, strong ect, again.
the only real way out it to leave, but thats hard to do, alot of times your locked into this persons life through marriage or children, and if the person is crazy enough and most times they are theyll find you or at least you think that. and its true by this point you are alone youve been alienated from your friends and even family, but i think what people forget is that your friends and family will always take you back, at least your family, in our case our friends would too but were all lucky and to be honest none of us would ever let this happen to a friend.
anyways the bottom line is that these people are preditors and the prey on the weakest because they wont fight back, because there not real predidtors there just weak minded bitter resentful people for whatever reason and they will get theres on the end weather it be death, jail, beaten, or the worst fate i can think of, being alone forever.
