First of all, I am not sure what happened before your loved wife stopped talking to you. I believe there's a reason behind everything.
It will be 10 years since I started the relationship with my husband and we are going to celebrate our 6th wedding anniversary in August. I, as a gemini, loves variety. I love to bring freshness into our life from time to time. It could be a new dish that I learned to cook. It could be a new travel plan for our holiday. It could be popping onto a bus and going to a place that we've never been when we were initially just going for a walk after dinner. And yes, as Loyless said, I do like to study astrology of geminis and agree that gemini people are restless. And I'd expect my husband to enjoy the ideas that I brought in.
Do you find some similarities in your wife? Do you know what she likes and what she really wants?
I believe marrige is a life long project that both parties have to put a lot of effort in, esp. when you have two kids together. My husband and I don't have kids yet, but I already feel sometimes he doesn't know what's on my mind. Even when I talked about what I was thinking, he sometimes misunderstood me and acted rather childish. For that, I explained as immaturity. But this makes me feel very tired, after years of living together. I think this is part of the reason why I was attracted to that Aries man who is 13 years older than me. I thought he is mature, he knew what's on my mind. He spoke the words that I was just about to say. Maybe he is a skillful player, as DreamerNorth said, but to me, when I felt tired in my relationship, he did attract me instantly.
However, that doesn't mean that my love for my husband is gone. Never! All the time when I "flirted " with Aries man, I was debating inside, accusing myself doing what I had done and I felt very very bad about myself because it was very unfair to my husband, the only man who has ever filled my heart in my life. I tried very hard to convince myself I must not do anything harm to my husband and must stop flirting with Aries man. And so I came to this forum and pleaded for help when I felt I was loosing my strength.
I hope you would try to find out what really happened between you and your wife. Only when you know where the problem started, could you find out a solution. Maybe you would like to talk a bit more about you and your wife so that I could try to help, from a gemini woman's point of view?
