Definitely, what is more important? A dog or a strange man after his gf. I called ur ex a stranger but he is worse as he was ur ex and he should care more for his daughter than anyone else. Why wd he try to spoil the day by silly childish actions towards you? He needs to behave like adults. I do not see a point of telling his gf, she cant stop him since he will have the excuse 'i am going for my daughter's wedding' and that is a good excuse for him..
