Ok. now I've read the whole thread .... - I hate it when other people say 'I haven't read the whole thread BUT...' and then talk rubbish because they don't have all the facts, and then I go and do it myself!!!
So. Now I've read the whole thread [hypocrite emoticon] I can see that it you are actually mad at your dh for working through his annual leave, meaning you didn't get your booked family holiday, AND deciding to work on his daughters birthday THEN saying you had to slot her celebration into a tiny window of his availability.
I would be mad too. I can see how you can feel that he is placing work before you.
Unless he is being put under pressure at work to do this, or there are threats of redundancy or something, then I actually think HE is being unreasonable. Naturally people want to shine at work, and to impress, but you can do this without sacrificing things so important to your family.
Work/home is a balance and of course there are many times when work takes priority, of course it must, it is bread on the table.
But I think your dh has gone too far on this and I can see why you are upset.
Basically, what you are saying to him is "fine, we'll just get on with life without you"
I personally don't think it is the best way to deal with the situation, but I can understand the feeling. It seems you feel unimportant to him and you feel that the child you share is unimportant to him.
