I had the situation before. I simply asked them what was up, was everything all right and etc. They never really gave me an clear answer but wanted for us to stay in touch. Fuck that - it's either 100% or 0% - no in between. So I dumped her.
Point is, preserve your dignity - don't wait for the other person to somehow regain that interest.
