Composite Mars in the Eighth House

This is likely to be a deep and very intense relationship, where there is a certain element of obsession and compulsion in the way you implement it. As a love affair, it will likely be intensely sexual with a very heavy emphasis on physical satisfaction even to the detriment of emotional understanding. If less intimate in nature, it will still be characterized by a need to chase after the seemingly unknown and inaccessible, which can either lead to disaster or to achievements no one could have dreamed were possible. The key is fascination with the unknown and the determination to make it your own, whatever the price. As long as you have something slightly ahead of you to chase down, you will have plenty of get up and go. When nothing is on the horizon, you are likely to be bored and irritable with each other, so keep a challenge ahead of you at all times. As long as you have something to feel intense about, your fires will be well fueled. On the purely professional level, this is a good position for handling other people's resources, and good credit can be a major factor in empowering you to get where you want to go.
