My child has always had a great relationship with her other parent (we separated when child was 2, child is now 13) always spent quality time together and had a genuinely lovely, fun relationship.
Other parent met someone else and everything seemed to be fine and rosey, never had any issues or concerns.
They recently married and EVERYTHING has changed !!!!!!
My child is rarely allowed to stay at her other parents house anymore (the family home where the child bought into as a newborn baby, the home before Step Parent came along).
Step Parent has trouble sleeping so needs the marital bed to herself - forcing the parent to sleep in the child's bed... meaning child has nowhere to sleep so is constantly being let down and having weeknight and weekend visits cancelled to suit.
Plans are made for child to stay over and then cancelled with little warning, leaving child feeling upset, rejected and pushed out. There have been weeks at a time when she hasn't seen the other parent - due to Step Parent needing to "rest". Step parent moved out for a few weeks and things went back to normal but my child, but as soon as step parent moves back... things change and my child is no longer allowed to visit (this has happened 3 times so far this year).
Child feels awkward and uncomfortable around the step parent because of this and doesn't want to be around them / doesn't feel secure or relaxed in their own childhood home anymore.
It is absolutely heart-breaking to witness and I am fed up with it. I don't want this hurt for my child, but I also don't want to cause arguments/awkwardness between me and the other parent - for my child's sake.
Have tried to talk to other parent but they defend their spouse and say they need to do what's best for them... forgetting about our child and their feelings.
Other parent denies / doesn't accept that this is causing issues for our child and believes all this behaviour is fine and normal.
I just don't know how to deal with the situation anymore. Child is at a very sensitive age.
