im writing because I'm a step parent of a eight year old, I'm really struggling with the fact that me and my partner have done everything we possibly can to try and work reasonably with his ex but is has come to the point that no matter how nice you put things, are understanding, encouraging etc she really is impossible to work with - we have child arrangements in a written plan so its not like we really have to think about the day to day stuff but she doesn't do what she agrees to sometimes for example handing over simple stuff like if the child has been sick, lying about doing his homework with him , buying him aged 18 figurines when the child is eight ! not telling us when the child has been to the doctors and to me its infruriating that she simply , obviously is doing it for control rather than understanding the impact on the child because shes rapidly jealous of the fact that her ex and I are moving on- she was the one who called it off and cheated on him- but he divorced her for unreasonable behaviour I can see why !!! She is nasty about me - making things up about me that simply is not true , sayng that I am saying horrible things about her when I'm alone with the child - saying that the child has said this when I don't believe this for a second as we have a fantastic relationship- but this was all said when my ex gently mentioned the above ! it really is draining , it is coming to the point now where we are agreeing with each other ( me and my partner and my step childs dad) that we are not even going to interact with this person , because rather than trying to get any info out of her we will just speak to school , the doctors and hospitals ourself because it really is easier . It really does sadden me deeply that the childs mother is like this and has to make life so hard for everyone involved but I think I need support to let go of the fact that sometimes it does not matter how much you want something to work for the sake of the child - it simply doesn't sometimes people all though they say they want to , in their actions show they don't want to change and its about doing what myself and my partner can do for the child whilst they are with us - anyone else in this position /gone through it? sometimes I feel like I'm the only one !
