DP and I had joint wills created. Leaving custody of children to both sets of grandparents for now. DP not signed his copy, states he only wants his parents to have custody if the worst occurred. Both grandparents are so far well, mine live 10 minutes away. In-laws 6hrs away. DP states my parents have no friends or family to help, and he has concerns about my mother’s mental health. I’m gob smacked. No idea how to react to this. My parents helped endlessly with childcare, DIY. I am an only child also. AIBU to be hurt and confused by this?
