I hate my boyfriends mother!?

My boyfriend and I have been going out for over a year, I love him but I hate his parents! His mum is soo highly strung and SUCH a drama queen and my boyfriend and his dad indulge her in every freak out she has! She got a call from the doctor to say she needed some blood tests, perfectly routine, and she rang my boyf in tears about it and he had to go see her, and he and his dad had to take her shopping to cheer her up about it. He's an only child, still lives at home at 22, and doesn't see anything wrong with the way she is. Shes extremely over protective, wont let me stay over at their house and wont allow him and me to be alone in the same room (although he stays at mine, she thinks he sleeps on the sofa). He won't move out of their house because they are such a co-dependant little trio and he cant imagine leaving them. I love spending time with him when its just us, but am I wasting my time? Im a very laid back person and cant stand all the drama, should I end it? coz he is always going to run to her whenever she freaks out about any little thing. every time i go round to their house i have to tread on eggshells so that i don't upset her. me and my boyf argue about it a lot, is his relationship with his mother meaning our relationship is doomed? or should i just get on with it?
