Daughter Finds Happiness By Ghosting Mother, Siblings

DEAR ABBY: I’m in my mid-30s and about a year ago I went from limited contact to no contact with two siblings and my mother. No single incident caused this, nor was there any history of childhood abuse, etc. I just find I am much happier without their presence in my life. I am married, content, take joy in my job and am otherwise fulfilled. I do not miss their general negativity, peevish behavior or critical comments. My question is this: Do I owe them an explanation or a place in my life? I am generally an unsentimental person. I try to be fair. After years of not enjoying our contact, is it OK to finally end it once and for all? -- DETACHED IN TEXAS
