So we told dh's ex about our family holiday all the way back in early January. It is something that we saved for a while and due to the size of the family 5 dc it is very expensive.
She now has said she has booked a holiday and this overlaps with our holiday. She said that she could find no other dates to go and that this was the only time she could go and that she is taken dss (16). Dh is really angry at her for doing this and putting the question of what holiday dss wants to go on. This is part of a number of problems that she has caused trying to cause conflict. She told dss that he should call her new partner dad.
Another issue is that she does not take any interest in her sons behaviour or schooling. My two of my dc are in the same year at school and he had no one turn up on parents evening when his mum said to dh she was going to go. Dh was more than willing to attend but she said that she would go and report back to him. She doesn't stick to discipline with us and when dss does something bad like steal money off me and my dc she doesn't treat it seriously.
She does not work as dh supports her and fair enough she is the mother of his child but it's getting to the point where we are thinking of not paying her so much. We pay way beyond what the child mantainance is and we get it all thrown back in our face when she books a holiday the same time.
She tries to turn dss against dh by saying things like he was having an affair with me (complete lie).
She demanded that that dh should leave me alone when my son was in hospital and drive dss to her as part of arrangements. When she lives a mile down the road from us.
But the holiday thing is really taking the puss aibu.
