I'm afraid it may not a good pair. At first, you may get a good relationship because you love each other. With the time goes by, the heat will gone, so they may tend to fight in their daily life. Snake can be jeaslous which may be a risk for this relationship.
However, if you love each other, you can compromise to each other and everything can be solved easily.
