My Husband and I agreed to have my disabled Father come to live with us 7 years ago. He is 72, diabetic and has lost both his legs (below the knees) due to self neglect, not managing his blood sugar levels etc and smoking heavily. He wanted to come and live with us and we converted our garage into an annex attached on the side of our house (he paid for the conversion with some of the money he got from selling his house). We live with a link door in-between. The problems have arisen over the last 18 months as its become apparent he is a serious alcoholic (1/2 litre bottle of vodka per night) and watches pornographic films for hours throughout the day with no attempt at keeping it discrete. This behaviour is obviously unacceptable especially as I have an 11 year old son who is in the vicinity of his Grandfather. Despite all this I still feel terrible guilt at the thought of asking Dad to leave. I have given him an ultimatum, he keeps his behaviour private or he moves out. He adopts a very passive aggressive behaviour and just sulks rather than discussing the situation. I feel very upset and trapped.
