help please!!!! I feel like a teenager again.

So, last year, I fell pregnant. With my daughter. My family can't stand her dad (my partner)..... so I moved out and got my own home. Just getting all settled and getting it all decorated for me and my boyfriend finally living together (due another baby) and now my dad has landed down to live with me because my mum kicked him out 😭😭😭😭..... I feel like a teenager again, living with my parent. Now my boyfriend can't stay over, I can't smoke, I can't invite whoever I want around. And I know he's not going to leave again. What do I do. How do I get rid of him.
