Have posted this in mental health too but not sure how often those boards are visited.
FIL has told us, (me in fact, but saying it was info to share with dh), that he is suffering from stress and depression and that he is getting help from his gp and a carers group (he cares for MIL). We see them about once a month - they are a couple of hours drive away. He is a very quiet and rather odd man, he likes to say hello for half an hour then disappear up to his study to play on the computer, or will stop a conversation halfway through and put the tv on then ignore you.
Anyway he said MIL was not to be told about this in any circumstances.
Presumably he is telling us as a cry for help. What should we do. My DH is reticent talking about feelings but I told him he needs to go out for a walk or drive with his dad when we see them next and I will stay with MIL or baby.
Also we won't tell MIL but I do not feel comfortable keeping secrets. I would not from DH and we have an agreement that if ever asked to keep something from each other by our parents we would just say no, that we tell each other everything.
