Similar to this question, except it just started yesterday, and the child is 3.
My son is 3, turning 4 next month. My ex was inching to take away my weekend visits, and I compromised (since it's summer). She then tried taking away my one weeknight from visitation, and I said no. She turned hostile towards me, and I did my best to ignore it.
She promised to take him fishing on my week day without first checking with me. After I said that I had plans with him on that day (during my time that the consent order we have in place says), she told me that I had to tell him that I'm cancelling his plans to go fishing. And yes, after researching about PAS, I know that's a classic start.
After I picked him up, he seemed normal. I always say "I love you" when I buckle him in before driving anywhere, even down the street. After we got home, he said he wanted to go back to his mom's, repeatedly. I asked why, and he said "Because and mommy said so". He still listened like he normally does, but this behaviour only started when I denied her request to take away all my time with him.
This morning, before I went to drop him off, he was back to normal: said "I love you" to me, cuddled with me before leaving, etc. I felt a bit better, but I still feel extremely powerless in dealing with this issue.
In my province, there is no law against a parent alienating the other parent to the child. Custody would not be granted on this basis alone. According to many experts, I should just leave it alone, and always tell him that I love him, and never bash his mom and step dad (which I never do anyways; I've heard too many stories of messed up minds in teens who believed this nonsense was about them). So my question is, with such a young child, what can I do to rectify the issue, and make sure he always knows I love him, no matter what anyone else says?
(I'm sorta new to this particular SE; if I tagged wrong, please fix)
