Kevin - I don't know if I am responding to you or to me. but of course distancing yourself from her will give you the feeling that someting is missing. Something IS missing. But distincing is something you have to do to get that something back. If you are both happier when you are together then do something that eases that emptiness when you are apart and let the vaccuum of no or little contact pull her back to you. I favor a little contact since it keeps you in her thoughs and does give you the chance to make any contact a very plesant one so she looks forward to the next one but not enough contact to give her the idea that you will always be there.
As to why she feels the need to find someone else before giving herself a chance with you - I think that like my wife, she has convenced herself that it is over and there is nothing that can make it work. with all your contacts being very plesant and happy experiences your love will continue to chip away at that belief one little chip at a time.
It takes a lot of effort to rebuild the R and only you can decide if it is worth the effort.
