I don't understand the message I give guys?

because you are not being up front with what you want. You have to tell guys what you are looking for in a relationship and if they are honest and tell you they dont want a girlfriend then you have to drop them like hotcakes. You are in control of what you want not them. NEVER SETTLE-IF THEY CAN'T GIVE YOU WHAT YOU WANT THEN GET IT FOR YOURSELF.
