My son stays with his dad on weekends however he was ill this weekend after having injections so I told my ex husbands mum, who was meant to pick him up, that he wasnt well and that I was keeping him with me. She seemed to totally understand however when she visited today she went back and told my ex husband that I was lying just bcz my son was happy and playing nicely. He didnt seem ill to her im guessing. Hes had a temperature since weds which seems to spike at night so he has sleepless nights. She isnt exactly seeing that. I feel really annoyed that shes come and spied and then allowed my ex husband to send me abusive texts off her phone. Am I wrong to have said she is not welcome anymore? This would then mean that my son will not stay with his dad on the weekends. Not that it helps, 99% of the time he comes back ill and upset.
