First, condolences on your father's passing.

Second, I am having to cut nearly everyone in my family out of my life for many of the same reasons. They are toxic and cause me more harm than good. It isn't an easy thing to do because I occasionally yearn for the good old times. It is hard not to pick up that phone when I just want to hear a particular voice.

Like Toejam said "You have your own life to lead after all and no one can do for you but you".
