Hey John,
Did not mean to be harsh but I see you doing the same things that got me no where. As a matter of fact I think my ex would leave her phone laying around so I would snoop and she knew the tailspin it would send me into.
Its very,very hard to detach. But if you don't do it now John, you will be like me. And post divorce detached is not where you want to be.
Again last night when I got the kids back from my ex she expressed an interest in picking out colors for my house with me. Use's the excuse that since she does do real estate still, that she could help me.
I'm a big boy but my buddy tends to think she is planning on asking to get back together and is setting the table.

Now remember. Remember when you went away with the kids and came back what a mess she was. Emotionally you need to let go for a while. You must resist all urges to pursue.
She will bait and bait you but until you see some real changes you can not fall back into it.
Then she will pursue, such as sex and you still can't fall right back into it. Its the only way that she will truly change because right now she is manipulating you and counting on the fact that you love her and will do anything for her.
Don't rescue her anymore John. Let her fall and feel the bump.
Best of luck Rondo
