There is a huge backstory to my relationship with BIL but I'm trying to keep this as brief as I can.
BIL is a total narcissist, has been with his partner a long time but no children.
We have 2 DC, a few years ago my DS started to really struggle, he was very depressed and had an eating disorder.
He is a lot better now but still sees a therapist and I really believe he has ADHD.
BIL does not believe in ADHD and when DS was struggling he would offer to meet up with him. But it would be "I have a 45min window on Weds for a quick coffee".
A lot has happened in our family the last few years and BIL hasn't been supportive.
So, to my problem. My DH has been diagnosed with cancer. It's going to be a long journey of treatment and life changing surgery.
BIL is very concerned and has been involved with treatment plan and researching things.
In one phone call to me he said " I have been feeling so ill for the last few weeks worrying about this. I know you must be but after all he is my flesh and blood!"
We arranged to meet up with them for a meal just before DH first hospital stay. I must admit I had a few drinks (we had just been given some awful news). BIL began to complain about my son, I snapped and said I don't think he has been very supportive of him and he hadn't been supportive of me either. I had a mental health breakdown in 2022 just as DS was going to uni and was admitted to hospital for 3 months.
We had an argument, DH and SIL didn't say anything. The next day I messaged them and apologised. I said the most important thing was to concentrate on DH care and treatment and let everything else go. They both agreed.
DH had a 7 day hospital stay, I went everyday but BIL didn't visit once. Since DH has been home BIL has not offered any help. He does phone DH every day but no offer to take him out, visit etc. DH cannot drive at the moment or lift so everything has been down to me, including getting elderly PIL shopping.
Although I really don't want to spend time with BIL I'm increasingly getting angry at his treatment of me. I'm so confused why I am feeling this way because I don't like the man and it's a relief not to listen to him.
But I just don't know how to process my anger? And also if I'm justified? Any advice please?
