I am GEMINI and she is SAGITARUS.

I am Gemini too and i know my style. =) i believe zodiac will let us know more about the characteristic, thus if you understand more on that, it will somehow help on the relationship. But not to over depends on that as we are human, we can't be predicted. Thus, be passion and have open discussion and telling what you feel and what she would like to work together to solve the situation. Hope that helps.

Yeah, most Sagitarus women I know are rather overbearing and controling. My ex husband was a Sagitarus, he was a liar and a cheater. My present husband is a Gemini, and he is very tolerable and laid back, I am a Cancer. I do not know whether signs have any relevance in your relationship, but Have you spoken to her about this. Let her know that her possessiveness is weakening your relationship. It's hard to change the spots on a leopard, but maybe she will try to calm it down some. Wishing you luck

I do not think that your relatiionship is physically attracted and mentally due to your signs. If you really love each other, you have to show maturity and try to resolve your diffierences. If she is possessuve, you have to accept her in the same form at once and then try to make her feel that being over possessive will not be good for her and she must give you certain liberties. May be she has some complaints against you too. Try to know what she does not like about you and tell her that you will try to change yourself as you love her. She will surely respond positively and will try to change herself too.
