How old is your stepson? Your ex sounds completely mental. Here's an evil thought, not that it matters. She says she wants to co-parent more, you find out she has a new f-buddy, and suddenly she allows you to take him every other weekend freeing up more of her time. NOT that it matters at all! You get to spend some precious quality time with you kid! Her loss again and again.
