I am fully expecting to get flamed for this and my view is very much clouded by my own experience.
But sometimes I think that it would be better if when parents separate only one of them have parental responsibility to prevent children being used as pawns.
I get very nervous about broaching things like schooling with my ex as I know he can override my decisions and tends to disagree with me for the sake of disagreeing. There are many occasions where he has made my life difficult just because he can.
The children currently do not know whether or not they are getting on a plane to NI tomorrow as their father is exercising his 'rights' and not telling me whether or not he is taking them. I cannot promise them that I will speak to them as I don't know whether or not I will.
