I would help her in any way I could. I don't have an "X", but my husband does. When my stepson was younger and still lived with his mother, I would take him shopping for her b-day, mom's day, x-mas, etc. and pay for the gifts. I figured she and my husband made a great kid together and just because it did not work out for them, he did not have to feel bad about not being able to get his mom gifts. I think it also helped with my relationship with her. She also started to take him for mom's day and x-mas for me. Which did shocked me, since he had his dad to do that. You will feel better when it is all done and over. The time my stepson and I got to spend together then (and now) was and is priceless.
