Two girls, one choice?

I broke up with my ex about two weeks ago, but we still really love each other. But now she has feelings for someone and I do also, the problem is, is that I want to be with the other girl, but the other girl really isn't sexual like my ex girlfriend. I feel comfortable touching my ex and not the girl I have feelings for. I don't know who to choose, and who to lose. Its taring me apart! My brain is boggled up with mixtures of who to choose.
