I've read through your original post and all the replies thereafter. There are some very good points made. I think there is very little trust on her part of you and at this point a sensible amount of distrust on your part.
Where does this leave you? If she has made it a point to tell you she is not in love with you there is really is not much more to go from there. Love seems to be a little one-sided and is not being fair to you. Counseling/mediator may help the two of you figure this out then again separation while you are going through this may be the answer.
