My ex and I have been separated since my oldest son was 14. Everytime I feel like we are making progress on the co-parenting it always sends to show its true colors. One of the biggest issues I have is that he always goes back on what we agreed upon, what we said. For instance, our oldest son has had the hardest time teeming the truth and a marijuana problem. Although we went to dinner with all parents and agreed that he could live with me one last time under contract( mind u he's 19 at this time) and that was for the sack of him and his confident bad choice making and being with our youngest kids that if it was broken in any way he could not go to the other family home or live at my home anymore. Needless to say about 6 months ago I had to follow through and it killed me, but it was best for the younger ones. Now i find out that he is allowing him to move back in and not only that didn't even tell me himself, i had to hear it out of my younger ones. This is delicately not the first time. I just don't know where to go with this or what to do. And they told them they weren't allowed to discuss it with me, but why couldnt he couldn't. I don't want my son on the street but we keep enabling him.
