Yeah, I'm confused too, Tyler.
You said you moved away from your parents and closer to your son, but then you said you were living with your parents again?
I agree with HorseLover. Your wife and you should discuss the issues of visitation and it shouldn't be discussed in front of your son first. That could easily end up with him feeling like he is caught in the middle of trying to please you both. And, it makes sense that your ex is being cautious with you seeing your son. She wants and needs to protect your son, and she may not be sure of you at this time.
When I was in the first months of sobriety I wanted so badly for things to be 'okay' and for everything to be fixed. It didn't happen that way. It takes a lot of time and a lot of patience. Hang in there and you will get a chance to know your son and to spend time with him. I think it's great that you're working on mending the relationship with your son.
