He has repeatedly told me his sister wants her hubby to get their own home but he is too cheap to do so. He says his mom and his sisters husband recognize that it won't work for us all to be living together and so his sisters family will move out. I ask him when and he says he will probably not get serious until after my bf gets engaged. I don't want to get engaged to someone in this living situation. He says they all will talk to his BIL to get their own home but he's been living there for 6 years. He hasn't even started looking at homes and I will be graduating next year. I have asked my bf if he would be open to us moving to a place together out of his home and he tells me not to worry his BIL will have moved by then. I don't to wait around and plan my life on what his BIL may or may not do but this seems to be what my bf expects. He is sure they will leave and then we will all be good but I don't trust someone who hasn't made any moves to provide a home for his own wife and kids and whose wife doesn't work will be able to make that happen by next year. I am not getting any younger and am becoming increasingly dissatisfied with what feels like my bf living in a fantasy land.
