Heya
Ranting cna be gud...lets things off ur chest...i often rant 2 myself (i'm strange lyk that!)
You have very right 2 moan so don't b sorry :)
I know what it feels like to a degree having the caring role taken off you, but not anything like your sitaution. You said urself that he's in good hands and so make yuorself priority for once. We all deserve some time to ourselves and it doesnt mean u dont luv him any less. Think of it as somebody is giving you a break, you need your own life as well and although i know we feel like we shud always care for our loved ones, as im starting to realise sometimes its better for the person your caring for if you have the odd break now and then.
Sorry if this doesnt help nd i know its long, but keep strong nd tke care x
