Would you feel guilty about not liking and ignoring your relatives?

I have relatives (grandmother, aunts cousins, etc.) that I don’t like and I try to avoid them. They call ocassionally to ask for a favor and I don’t return their calls. When I was younger they were horribly neglectful to me and growing up they never helped me when I needed help the most. They don’t visit my home and my grandmother doesn’t display pictures of me or my kids in her house. But she has pics of everyone else. when they call the just ask for what they want, they never ask how my kids are doing. I dont think they have even seen my kids in the last 10 yrs. No birthday cards or calls. when i needed a place to stay back when i was an unwed teen with a baby, they all turned their backs on me. Now that I’m grown and happy and they are not really happy with their lives they want to call and be my friend. They are not family, they are relatives. BIG difference. I have decided that I won’t answer any more of their calls and that my life isn’t benefitted by having them a part of it. I just have no feelings for them. My grandmother is old now but if she passed away although I’d be sad for their loss, it would not hurt me very much because I didn’t have a relationship with her. It would be as if a stranger died. Anyone else feel this way about their relatives?
