I second what Andy is saying..... Give her space.... My W was in this ambivilent stage for a few months and I did a lot of the things that you are currently doing. I did date nights, I bought her a gift when I was out of town...That did nothing but push her further and further away. In fact she told me to stop doing this for her. That is when I did stop and backed off. Unfortunately it was to late for me. Your a good man, I know this is hard...really hard. But give her as much space as possible. Try to put your old M as far out of your mind as you possible can. Keep up the GALing, it will help in this area.
Detach as best you can, and enjoy every moment with your son.
