My mom passed away 4 years ago and since then I have been living with my step-dad and I have been granted probate on the house (I think is the right term to use?). I had moved out many years ago but gave up my council property to move back home and be a live in carer for my mom but since she has passed mine and my step dads relationship has deteriorated, he drinks and smokes a lot (I think he is depressed too) and although he loves my son (his grandson) and says he's his reason to live he doesn't make the house a very nice place to live. At all. I have also had a newborn baby (don't live with her dad because of the step-dad situation) and he wont stop having crafty cigarettes in the house (kitchen or toilet) as soon as our back is turned. Anyway this caused a HUGE argument in our house yesterday and he's woke up miserable/moody /bitchy today and caused another argument so on a whim I called the estate agents and have an agent coming round on Wednesday to assess the property. Its the only way I can see out and as much as I don't want to lose the family home or split my stepdad up from my son (son is disabled and they have a very close bond) its the only way I can see me being happy. Am I being selfish though and should I just put up with it? The way stepdad drinks and smokes he won't be with us in a few years anyway (harsh but true) so AIBU to want to sell our house?
