Hi guys this is my first post. I'm from the uk and have 3 grown up sd (24,29 and 30) and we have an 8 year old together too. My youngest sd moved into our basement flat and brought a friend for a 'few days' 4 months ago. They are not bad step children just the usual problems not bothering with birthdays for me, not engaging with their brother etc but this living situation is getting me down. They have a flat downstairs tv, fridge, microwave etc. they pay no rent although I have told them they need to pay towards bills from now on...I'll see if that happens. However they seem to see my house as an extension of their bit. I got several texts yesterday asking if I could throw toilet roll down, could they come and do their laundry and can they get into the kitchen to cook "because we need to eat". Now I don't want to share my house in the first place but I can't make my husband or them see that they need to treat us as neighbours rather than roommates. I want them to support themselves use their microwave and perhaps on a weekend do their laundry. If they don't like it they can go. Husband has issues about getting to know her as he left when she was 9 and he wants to set her on the right track and has residual guilt about their lack of a bond. We let the middle one live with us and she has a great relationship with him now but it was just her not her friend. I'm resenting everything about them especially the smoking. I hate smoking. Sorry for the rant I'm so down at the moment can anyone help?
