Your destiny is not tied to anyone who can walk away from you. Maybe you shouldn't be so concerned with dating for right now. Get happy with yourself, and get happy with being alone. Others are not responsible for your happiness...you are. You gotta bring something to the table stillalone. Right now, your insecurity sticks out like a sore thumb...and that's not attractive to others. Don't rush it, and don't look to others for your happiness. All of have felt what you're feeling...and lots of us still are. I think a huge step is learning to love ourselves unconditionally...and I mean deeply. Remember, the Golden Rule is based upon the premise that we love ourselves.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
