I would submit the first order of the day is to just get out and away from your H to do the thinking that you need to do...
Some serious soul searching, I think...
I'm not suggesting moving out or tossing him, just to be clear.
Just saying you need some YOU time, even if it means booking a couple nights at a hotel next weekend... He might become clingy and that might become annoying...
Yes, I think you're right that I need some time alone - his sad lost puppy expression is becoming annoying when it should be me that has that expression under the circumstances!! I'm still trying not to upset things too much at the moment, it is our S birthday at the weekend so I don't want to spoil it for him bless him but maybe the next available weekend would be a good idea!
