"Do I tell her that I am not giving up on the relationship but I am just letting her have her space and going to let time tell if it is meant to be?"
Don't you think telling her your game plan to get her back will make all you are doing lose its effect?
It's kind of like saying I really want you back, so when you don't hear from me it's because I'm giving you space so you can decide if you want me or not.
I think you need to trust yourself and the facts of what have been happening.
I'm replying to about 6 different people on this board now, and you are only one of two whose spouse keeps contacting them for chit chat.
And you are the only one (of the 6) whose spouse has said that you are the only one she wants, has asked to come over, has asked to lie with her, to hold her, to come back over.
What you are doing is working, so stay consistent.
