People like this are never worth your time, sadly. 🙄 My husband's father left them when he was 15. Younger brother 12, younger sister 9. Before that he was essentially a non-person and was more interested in his new “toys” than attend a choir concert, etc. He told me a story about one time the father canceled on them for their movie date. Their mom took them instead—- only to find their father sitting a few seats ahead of them WITH HIS NEW GIRLFRIEND.
My husband says he’s not hurt with his father’s actions, but deep down I think he is.
