Moving on again

So what do you do when she says she is moving country again. This time its a little more extreme. ? Its bad enough one time its Leeds then its Scotland but I cant fly to another country every week can I ? Law seems truly on the woman's side. I have done nothing wrong just want to see my kids. Its a simple as that however the law seems to let the mother do as she likes travel where she likes and just cut the dad out. I just dont get on with her and she dont get on with me. Now all that happens is the kids suffer and so does the dad.
