So, I'm still waffling on the correct approach to this situation.
I'm understanding to put no pressure on her. Is going to counceling pressure?
I guess I'll leave that up to her. I'm going either way. Am I supposed to act like I don't want her? She already knows I want her. She knows I want to save the marriage- she probably feels like it would just be more of the same. So finalizing the divorce is probably in my favor. I always look good around her. I'm totally hitting the gym, so I look great. I'm still wondering about texting and stuff. Keep replys short, don't always respond right away? I've been letting her ask me to go out to dinner with our son. I've really let her be the instigator of us spending time together with our son. I'm still wondering about the whole be unavailable. What does that actually look like?

So I was in class all day and I texted her about dinner, "I'm available for dinner if you guys want to go out" (not typical for me to initiate) she responded that the cousins were over and they were eating. I put ok that's cool I'll see you guys later. This is the part that gives me hope. She said "ok, how was class today?"
She could have just said ok and left it there. We went back and forth a few times with me sending my texts as if it could just end. But she kept adding questions(you know typical chit chat) This feels like a good sign of at least being friends. (She pretty much hated me before I found DB, cause I was doing all the stuff I wasn't supposed to be doing) so here is to small victories, baby steps...
