I have just found out that my mum has cancer, it’s a pretty miserable diagnosis and I am profoundly sad about it. My partner and I have been living together for 5 months and his son has been coming over to say for last month or so. His son is 16 & a nice enough lad, I have no problems with him. He’s due this weekend and my partner is going to collect him as usual, but I don’t want him to come. I am a mass of tears and misery and don’t want anyone around. I’ve told my partner that I’m not my shiniest and he replied that the boy is looking forward to playing table tennis, so he doesn’t want to let him down, but I don’t want him there. Any ideas how to handle this please?
