Hello and welcome.I agree the son seems to be behaving appallingly,sometimes grief leads people to behave very strangely.Years ago I lost my partner to cancer and his brother blamed me.It was very bizarre I think he thought it was something you catch from someone else.His mum told me years later he had forgiven me. Very generous of him,but I havnt seen him since and it doesn't bother me.I came here much later after loosing my husband.We were both widowed when we met,His previous wife's family blanked me but luckily his children didn't follow suit.
It is so very hard when loneliness takes over.Your forum name sounds very rural and as I live in a rural area it doesn't help if there are no social options.So I also rely on the virtual world,but we do have real world meet ups arranged here so maybe something will come up near you,.I have found this place to be really helpful and virtual world or not,feel to have made real friendships.
