Coach, I have four adult kids and two grands and I love them all to death. But i dont like them all the same. One has a problematic, difficult temperament and we are still as close as you can be to a difficult adult child two states away. But I think my other three adult kids are kinder. They are certainly kinder to me. For example, i will be shocked if Oldest thinks beyond himself enough to remember Mothers day and Im so used to his forgetting things unrelated to himself that I dont even feel bad about it as long as my other three kindhearted adult kids remember. And of course they WILL.
Its not about love. Its about like. And its human nature to like people who are nice to us more thsn those who are not. Love is different from like. Dont allow Daughter to manipulate you. You both need distance from one another and you in my opinion could do better taking great care of the oly person you can control...YOU!
