My brother was on the rebound from a relationship when he started dating and then living with a woman who was a bit scatty. I think he was pleased to have somewhere else to live and someone to live with and wasnt thinking long term. So after about 9 months when she told him she was pregnant he was less than happy. He is a bit of an emotional coward so was not really frank with her about how he felt at first. But did eventually come clean and say he could not make a life with her. And immediately started dating another woman while living with his then pregnant girlfriend or rather ex girlfriend.
He eventually moved out and moved on with the new girlfriend, who he later married and had two children with.
His wife was furious about him having a son with his ex and wanted nothing to do with the child. Although he came to stay with them occasionally she would make it clear she wanted nothing to do with him. So eventually my brother also completely withdrew from the relationship with his son. His son grew up about a mile away from his father and his half siblings but has never met his siblings and they dont know he exists. I have kept in touch with him. He has had things hard. His mother never established another permanent relationship and started to develop some mental health problems. The council flat he grew up in became very dirty and full of hoarded items.
He is very angry about how his father has treated him and that makes our relationship a bit strained as he feels i should in some way make his father behave better.
I have tried to talk to my brother about this over the years but its just made him and his wife very wary of me. This more recently seems to have affected his children who are now almost adults.
My brother has suddenly become unwell and has been diagnosed with terminal cancer and has something like a few weeks to a few months to live. I asked him if he would be willing to meet his son but he said something like "for gods sake dont you think i have enough to deal with, why wont you leave it alone".
I feel terrible for his son who may now never have a chance to meet his father or say goodbye to him. His other two children are really struggling with his illness and are not coping well. I dont want to stir things up at a time that is really difficult for him, his wife and his children. His son from the past relationship is fully grown but still struggling with his mental health. I dont know whether to tell him his father is ill or not tell him since it will only make matters worse. But if i dont tell him that feels awful too. He continues to live with his mother about a mile away from my brother. I just dont know what to do for the best.
