I had the reverse happen, years ago, and truthfully i never got over the scorpio woman.
Over the next 12 years we would weave in and out of eachothers lives for a short time, until now. A lot of things happened to us, and now we are awake and together and it is bliss.
Scorpios can be very aggressive in their ‘unsureness’ with a cancer. Its usually because they feel so strongly, and so deeply it scares them, where a cancer embraces it. Give him some time, and with action show him what real connection is.
If you really want to get out of it, you need to break all communication, and just move on. You wont really get over it, but itll fade in time. If you entertain the reach for keeping in touch though, that should tell you something about what you really want.. life is to short, follow love.
