Oh honey! I am so sorry you are going through all this! It seems like you have been dealing with this for quite a while now, and I think that's probably an indication that you've really thought it through so that's good. I just want to say that it really seems like the problems in your relationship aren't your fault. If he is that controlling and that self-involved, you definitely deserve better. All these "rules" that you're talking about seem absolutely ridiculous! I can't imagine how you've put up with it so long, being told when you're allowed to get up and who you're allowed to socialise. It's like my sorta in-laws here, he doesn't let her use the car, he puts a bar on the phone so she can't even use her own phone, etc, etc and it makes me feel so bad for her. And I would hate to be, or for any of my friends (and you too!!) to be in a situation like that.
The other thing is, you have an illness (or whatever) that means that sometimes you might need more support than someone else. It sounds like your boyfriend not only doesn't offer you that extra support, but does the exact opposite! You aren't crazy, and the last thing you need when you are feeling unwell is for someone to behave in a way that makes you feel even worse!
I agree with Janey about the time thing, I would try and leave it to the last minute before you can actually leave. If he is so controlling, I imagine that the time after you say the word could be really awkward and unpleasant. I'd secure yourself a place to go (even temporarily) and then tell him what you are doing, and then you can just leave. I really hope you can get out of this as easily and smoothly as possible, and your quality of life will really improve if he gives you stress that makes your tummy bad! Good luck, we'll be here for you!! *hug hug hugs* Luv Steph
