My 21 year old step daughter no longer talks to her Dad and I, she sent her Dad awful messages, called him all sorts all because she felt he didn’t contact her enough, his oldest Daughter visits us often with her kids so I know jealousy is and always has been a big issue. The last message was her wanting closure and explanation why he’s such a bad Dad. I feel so bad for him as he’s mentally not coping and struggled since covid but also angry towards her, she must have a short memory as we done so much for her even took her in for 3 years when her Mum kicked her out until she decided to move in with her BF. My question is my Husband sends her £ every birthday/Christmas but she never acknowledges it, not that we expect a thanks, should he continue even when she has been so horrible?
