what are my rights as a grandparent and ability to see and spend time with my granddaughter..i am being denied for no real reasons.

These maters are always "complicated," which is why no email response is ever quite adequate, and the questions are never "simple."  In short, per the U.S. Supreme Court, fit parents have the right to determine with whom their children associate -- including grandparents.  That said, there is a satute relating to grandparental visitation, with its own restrictions and rules, which is explained to some extent here.  For a better explanation of the circumstances, risks, and options in your particular case, yoiu should seek a consultation appointment with a qualified family law specialist to go over all of your specific facts.
