I live in a three bed house with six other adults and am the only non family member but there is now a baby to add to everything. I was going to move out as soon I they told me about them having a baby. Also the mum asked me to move out by Feb but then about a month later had a break down in my room saying that she did don't want me to move and told me not to move so I have not done so. Our boss at work came up with the idea off turning the garage into anther room as we don't use it for the youngest son his girlfriend and the baby. But the youngest son never saved the money that he was told to by his mum so that went out of window. Then they came up with the idea of getting them a council flat to move to but that has not happened yet and I don't think that it will happen for a long time yet so now the oldest son and middle son share a bedroom with one sleeping on a blow up bed and the other on the bed each night taking it in turns. But I don't agree with this as they should not have to share and one of them has a bad back. The mum has also said about sleeping on a sofa bed and giving them her room but she has very bad knees and would be in a lot of pain all of the time. So I started to look for a flat to move to but am not sure if I can afford to as I am only on min wage and the rent for a flat near me is too high so I would have to move away and travel to work. But now my best friend has been told that she needs to move house as well as her mum is going to sell and she has asked to get a place with her, her boyfriend and their two and a half year old daughter but I would still need to travel to work. So I am asking for some advise as I am so very un sure what to do now. Please help me

I would never move in with a young couple and their child. You will most likely feel like a fifth wheel, no matter how much your friend needs to save on rent. Maybe if there were another girl with 4 of you chipping in.
I'd stay where you are for now, and start looking for female roommates to share with, either established ones looking for one new person, or all go find a new one together.
I have a feeling that you might be the only one with a steady income and the only one paying a steady rent, and that's why you are wanted where you are. Don't feel sorry for the sons if they aren't contributing to their mother's costs.

Well we all are working full time apart from the new mum who has never had a job and does nothing around the house to help. And thank you for your help
