Dd, 6, felt ill after school yesterday. She had a temperature, earache, off her food etc. ExH was supposed to be collecting her from school today but as it seemed she wouldn't be going I asked ifhe wanted to collect her last night instead as it's on his way home from work and it saves him the hour trip here. He did so but has called this morning saying he thinks dd has chicken pox and wants to bring her home now as his gf is pregnant. His gf has had it twice and though it's unlikely she'd catch it, I appreciate them wanting to be careful.
However, he hasn't seen dd for a month and won't again for another three weeks. I've had no time to wrap presents etc and this was my weekend to get organised for Christmas. Dd has had a sickness bug and ear infection in the past month and my other dd has been poorly too so I've had countless sleepless nights looking after them, so much so I've developed eczema which is a reaction to being run down according to my doctor. Dd is upset and asked that his gf stay elsewhere as she hasn't seen her dad for so long. Her mum lives round the corner so she could do that. ExH, however, said its her home too and he's not going to ask her to do that. Dd said 'i thought it was my home too?' 
AIBU in thinking it shouldn't always be up to me to deal with everything? If dd had had chicken pox when I was pregnant it's not as if I could or would have shipped her out until she was no longer contagious.
