Just stopping by to see how you're doing. I agree with K and everyone else about not being a martyr to your Mum. Why not experiment with a 180- say you're going out and that she can either stay in, or you can arrange for her to go out with XXX or XXX. No option for you to stay in.
BTW, I notice that in an earlier post you said that 'she makes you feel guilty', (or something like that). Sorry if I sound like a broken record here, but the only person who makes you feel like that is YOU! Choose to not feel guilty, and to feel confident, assertive and worthy instead.
