Four years ago,on the telephone with my 26 year old son,literally mid sentence with some inane weather comment,he suddenly said "that's it,I don't want to talk to you ever again" and put down the phone.We've never had any problems,talked frequently,I saw his two children,he was very thoughtful.Absolutely no reason and he has stuck to this.He's moved twice so I don't know his address,just the rough area.His fiancee is lovely and sends me pictures/updates of their children but she has no idea either about the reason for this..I think my son may be aware of her contact-not sure.He doesn't talk to my daughter,his sister,either.I send money for birthdays and Christmases to him and the family(he has never changed his bank account details.Obviously I can't touch his account,just send money to it.)I know he gets it but never acknowledges it although his fiancee always thanks me.His favourite place in the world is the small Scottish village where I was born and he visits frequently.My mother,,who he used to love dearly, still lives there but he never goes to see her.She died in August but again no acknowledgement and he didn't attend the funeral.He and his fiancee are getting married in this village in June but no invitations for myself, his sister (my husband,his father,died five years ago) or anyone in my family.I have absolutely no idea at all what brought all this about-that's what makes it so hard.I haven't done or said anything at all,he had a normal childhood and everything was fine until that phone call.His children will be my only grandchildren as my daughter can't have a baby so I'm missing out on them as well.I've done my very best for all these years to keep the channels of communication open although with no address it's difficult and I'll continue to do so but it breaks my heart.I know everyone will just say to continue with the limited contact I have and I'll do so but I don't know what else to do.
