I don't know what to do :(

My dad kicked my mum out when I was 12-13 weeks, I offered her to stay with hubby and I thinking it was only temporary but I'm 36 weeks now and she's still here! She has no money to afford a place of her own but I don't want her living with me anymore! I want some alone time with my husband before the baby comes. What am I supposed to do!? I know this is unfair on her but it's also unfair on us, I don't want to live with my mother anymore - I moved out of home 7 years ago :(
