I am a Horse man deeply in Love with an Ox woman, will it last?

I am a Horse Man whom is deeply in Love with an Ox Woman. We get along wonderfully. We communicate, long for one and other, and deeply enjoy our time spent together. We also know when something isn’t well with one and other. We are recently married and I know she is the best thing that ever happend to me. Also I am a Taurus and she is a Pisces. Do you believe it will last until death do us part? We have a child on the way and I will do almost anything to make it work between us.
