My dd, visits her Father at his Mothers every Monday and and every other weekend.
For the last three Monday's he has said he can't see her, as his girlfriend is going into hospital that day and he needs to pick her up and look after her.
No alternative arrangements were made with my dd and this Monday, she got the message by text.
(Begrudgingly giving the girlfriend the benefit of the doubt as she never speaks to my dd and has no children herself, lets assume the procedure she had done can only be carried out on a Monday and she's just not picking a Monday to be spiteful) What are your views?
