Oh BA. So sorry that it is so hard for you at the moment. You must be emotionally exhausted.
I feel so mad at your H on your behalf! GRRR!!
Very sorry about the accident too - am glad it wasn't more serious, but what an awful thing to have happen to you.
I think any 180 that you can do that puts some of the focus back on yourself has to be good. You can only experiment and monitor the results - if it doesn't work you can always try something new.
My little suggestion is that you don't have to make it really obvious with H. For example instead of saying "H I'm really tired and you are bringing me down can you please go back to your room". You could say something like (in a cheery voice) "H I've got a new book that I'm dying to read, (or I'd love to paint my toenails, or I want to phone my girlfriend) so I'll let you get back to your room now". And then go ahead and do it and don't give H your full attention if he stays in the room. Just a thought. I hope you get the idea of what I'm trying to say!?!?
You get an A++++ for not responding to your H's phone call about MOW. I would have exploded, with disastrous results....
Is there an new activity you could take up that you purposely exclude H from so that you can get a bit of peace and happiness?
