"I am doing things for her... Supporting her... Giving her LL... being kind..."
So you're doing it solely to get something back. If you're going to do something, do it for the sake of doing it. Think back to when you were first dating. You did stuff for her "just because". That's the attitude to take. If you you're doing it just for the sake of getting something back, then don't do it. This is all part of dropping the rope and attracting her back to you because of you. Not because of the things you do for her.
For lack of a better example (don't be offended here as this is only a figurative example): You're like the dog who is hanging by is master's side looking for approval. "look I can get your slippers" "look I can get your newspaper" "look I can roll over and look cute". In the end the master regards the dog but doesn't respect it. That's an extreme example, but you get the picture.
"I understand the concept but how long can one really give without getting?"
That's up to you. If you do things solely for the purpose of getting, then you will be disappointed every time. Because when she starts being receptive to you, you are going to be thinking she should be doing more. But those are your expectations, not hers. She will move at her own pace and you have no control over that.
