Seems to me that you were quite insecure about the thing going on between both of you.
And the thing that hint me for this was that statement of you:

I don't know what kind of teasing you apply but its plain cocky (without the element of funny) it comes as insecure.
Put your ego aside and think if its really like this. Its just a guess for me.
However if I'm right for this, response on your question will be - just focus on building confidence in general, do courage, strengthen your inner game. (it doesn't happen like finger snap - it takes time but in the long run is more rewarding).
