Hello,
Disclaimer: This is going to be a long family related story. It's not very exciting but I need some advice. It is quite long as I do not want to drip feed.
MIL passed away before DP and I got together. FIL now has a long term partner. My BIL (DP's brother) has been a difficult child, teenager, adult. He has a history of violence and strange behaviour, was kicked out of school, and was diagnosed with SN.
A few years ago BIL fell out with FIL. BIL asked FIL to choose between his son (BIL) and his partner. FIL refused to choose so BIL will not speak to him anymore.
Dead MIL's sister has been adding fuel to the fire. She does not want the boys to get along with FIL. She constantly brings up anecdotes on how FIL apparently misstreated their mother. The boys went to boarding school and they cannot actually recall incidents themselves. She also accused FIL of cheating with his now partner while MIL was alive.
BIL cannot cope with change generally. This situation is really affecting DP. DP loves both his dad and his brother. However he is torn from all sides.
I think that BIL needs professional help. However I am not sure how to help him. BIL has not very nice to me, but I bear with him for DP's sake.
How can we as a family help BIL and FIL to try to mend things?
