One of your needs as a Scorpio is to be in a nurturing but passionate and committed relationship.
If lately you have been struggling to even pass stage one in your relationships, giving your prospect the wrong idea might be what's happening.
Yours is a sign that finds it difficult to open up at first, and if you've been hurt in previous relationships, you might be making very difficult for someone to form a genuine bond even though that's actually what you really and truly want.
If someone feels right, showing your vulnerable side might be scary, but it surely can be very rewarding, Scorpio.
