ExP has decided he wants to 'go away' so can't look after our DC this weekend while I work. It's been planned for ages. Because I dared to say you can't just not look after them he's decided he won't have them tomorrow either (while I take DD1 to something- he'd agreed this last week). I'm so angry!
Frustrating isn't it! I have this problem too. What gets me most is that my ex cancels whenever there's the option of a night out, does none of the hard, boring work involved in raising a child then thinks he has equal rights to all the pleasant bits of his son - birthdays etc.
