I have been a single mum since my son was one. His father has always been involved but his career came first and I stopped work and brought him up as a working mum supported by benefits. Now he is a teenager he has all but disowned me and living with his father and his new family where life is more comfortable and money not an issue. I have been guilty of drinking too much wine on an evening but never to anyone's detriment. I am so upset - access is all on his terms now and I don't know how to break this unhappy cycle
