Hi Tyler....
I so applaud you for getting clean! You are so on the right track. Keep in mind, though....your ex doesn't really know the sober you. And....she may still have issues from when you were using, even is she doesn't admit it.
Slow and easy. And breathe. I do think you can have a relationship with your son....but it's gotta be slow, for your son's sake.
Horselover and Anna have some very good points. Again....a huge congratulations to you for getting your act together....this WILL benefit your son and you will see the results.
