I am SO glad that you got such good advice today - agree with all of it. And you certainly do have wonderful things to offer.
It would be a huge mistake if you were to continue to try to change who you are / what you feel to suit Gabe - that is not an authentic relationship. You, he or both will grow resentful with pretend.
Be you. We all love you, just as you are. He can either see the worth that we all can see, or he should get the he!! out of your way, let the door close so that others can (and would be sure to) open.
