DH and FIL haven't spoken since DHs birthday.
We usually make quite a big deal out of birthdays, for DH's significant birthday a few months ago FIL declined an invite to attend (no reason given) and sent a card late with a message enclosed saying that he hadn't bothered to get a present but would buy him a pint next time they saw each other. After phoning him to thank him DH had a look through his phone and basically saw that every contact made between the pair was by him.
DH decided to hold off contacting FIL and said he was going to wait to see how long it would take for him to get in touch. It's now been six months and two significant family events and they've yet to say a word to each other.
FIL does have form for this type of behaviour but since I've known DH they've had a loving (if a bit distant) relationship and genuinely get along really well.
AIBU to say enough is enough and intervene, DH is gutted by the fact his dad doesn't seem to be bothered by the contact, but all I keep thinking is that maybe FIL thinks DH is the one is ignoring him and now they're stuck in a situation where both are too stubborn to act.
Should I contact MIL and ask her to try and give FIL a bit of a push to pick up the phone.
Demand DH bites the bullet and phone himself.
or
Leave it all and risk DH eventually ending up NC with his dad.
