Ex husband has new wife but to my knowledge, she has nothing to do with father in law. To be frank, FIL was a useless dad and my ex was poisoned against him by his mother so has no contact.
FIL lives abroad and is mid 80's now. I know that for the last 30 plus years, he's tried to make amends with my ex but to no avail (ex is mid 50's and still very much a mummy's boy). I felt sorry for him, mainly because he's an elderly man and also because I lost my dad when I was 27, so it irks me that the ex won't engage.
I've detached myself from all of the exes family since we divorced but the FIL writes to me every few months, asking how things are.
Shall I write back or disengage ?
