you are doing great, the problem is after all that has happen it will take a few months of her seeing the new you for her to even think there is a chance, she needs to see that the changes are here to say and is it not a ruse to get her back to the same ol same ol.
Try not to say home along, join a running group, work out (your body will thank you) or volunteer, fill your time and go on mini vacations too with your son.
If she stopped going to C I suggest you do, I was becoming unglued even as I detached and coped well during my separation, you need someone to talk to, do you also see a psychologist since you are on meds?
You don't have to minimize contact with her, just dont' overwhelm her, it is ok to call her if she is ok with it of course. Have you tried asking her for an outing as a family? something for for all 3 of you, the zoo, circus, some show.
