A man will only do what he feels he has to do. This statement came from my Dad who got it right because he was a freedom lover too. I know my Mars Taurus guy loves his independence and is eccentric but he can be very stubborn about staying in a safe zone if he feels no need to move. After 5 years we were going no where and knowing that I was unhappy, he took the first step and called it quits. After a while we reconnected to have something deeper but that time out made him realize a lot of things he didn't have to think about before and we were able to talk it out and negotiate something that works for us, seeing as we have an unconventional relationship. Being Cancer Leo cusp and Libra Rising, I had thought it fair to give him every chance to commit to me fully on his terms, and I very clearly stated I wasn't going anywhere. But settling when you want something is not being happy. I realized that I could cling and hope or speak up and take control of my feelings, making the choice to be with someone who wanted to be with me the same way.
So aquarius is a freedom lover too and can be detached, as can Mars Taurus but Cancer Leo cusp is probably very loving and passionate and he might need that sizzle. Water and fire together can mean extremes and is a very challenging aspect when one is in love as well as like. She is also probably very fair and can see both sides of issues. I bet both people are good friends and this is the basis of the relationship, which could be solid. But if this guy doesn't want to rock the boat and take any chances on the future, then nothing will happen. Taurus can get stuck and aqua can be detached. If something is going to happen, it's going to have to be initiated by the female. He might not see any need to change anything. As much as Aqua and Taurus might love their freedom, they also sometimes need to take that leap of faith that pushes them to move from thinking mode to feeling mode and then find a balance between both. Once they realize that they also want more, then they can work on getting what they want. They can be very passionate in love but slow to commit. But if they want commitment, they give what they get.
