My DB has an idealistic view of how his life should be for him (mid 30s), with a doting wife and kid(s).
Despite having in my view a great life, doing well career-wise and he's had great opportunities to travel and do interesting things, he is miserable because he doesn't have 'the one'.
He avoids spending time with family. We barely speak because he doesn't answer and doesn't return my calls.
Sadly he admitted recently that he can't cope seeing us all happy with our partners and children and avoids contact to minimise the pain.
I know there's more to it, and he's emotionally damaged after our mum died when we were teens, but I'm convinced he'll never be happy until he stops being jealous of what he doesn't have, and focusing on the past as to why he doesn't have what he wants.
Any ideas how to help him. He's missing out so much and my darling dad is devastated as a lot of the blame of why DB feels life hasn't turned out 'right' is placed at my dad's door and stuff that happened nearly 20yrs ago.
