The good news is she has definitely not forgotten about you or stopped thinking about you. As a cancer woman, I promise you that is not the case. However, I think someone else mentioned this earlier, that doesn't mean that she is not trying as hard as she can to move on. Which means not contacting you and not responding to you.
Cancer women take very seriously letting people into their lives/hearts. Violate or disrupt that trust, and it will take an EXTREME amount of work and patience to build it back up.
If you really want to get back with her, contacting her three times in two months is not nearly enough. You are going to have to show that you are determined not to live without her.
I am not guaranteeing that she hasn't moved on. But I am saying that it doesn't sound like you have done enough to convince the average Cancer woman that you are serious about getting back together. And since you were the one that broke up with her, you are going to have to put in a lot of hours on this one.
