At the risk of disappointing you the answer does not lie in astrology but it lies in YOU and HER.
If she likes you and you like her and you have your HEAD, HEART AND GUTS in the right place, YES you can get married to her.
If she says no, respect it and leave her alone, if she says yes, go get her.
God has made you human and has given you free will, use it and if you really love her,
Let me give you a secret rule of Astrology: HEART IS THE BEST ASTROLOGER, COURAGE THE BEST GEMSTONE, AND LOVE IS THE BEST REMEDY.
