"Hey, do you need some time to yourself? If so, I'll leave you be for a bit."
Hi HollyB
This has probably been suggested but I think this is a good idea.
For me I like to have time to my self or things can get really over whelming. I need to rest and reflect. This could take an afternoon or it could take a few days when I am quite to be around.
It is nice sometimes when someone else suggests it for a change rather than me thinking that I am a kill joy for having enough or misunderstood when I just want some time. However I think it is important to say you are there for him if he wants to call and you will call in a few days to check in and see how he is. For me it would be a great weight off my shoulders and it shows trust and understanding.
I hope things have got better for you both.
best wishes
Saffy :)
