My father who is a crack/cocaine,crystal method, and alcohol addict is claiming he's dying of cancer (help)?

not to be rude but your grandma need to shut up.he most likely does have cancer because all those drug he took over the years. but since he has been taking drug mostly all his life there is no way now he is going to get clean that is a lie that he made because all he wants to do is live at your place. i don't think you should ever let him stay at your house because your children and he might steel your things and turn them in for drug money.i think you don't have to go i mean the man was not a good father to you so why should you care about him just because he is dieing does not mean you have to pity him. i think that you should go though to make a point and to clear things up with them and just tell them how great he was to you . well good luck.
