They married for Ruhi's sake. They both love eachother's families. They are both fair minded. They both take their careers seriously. They both can work hard. They do not shirk hard work. Both have a sense of duty, may be their views about duty may differ from prioritisation point of view at times. Both look good and attractive. Both are non clumsy. Both have lively dialogue exchanges,both indulge in nok Jhok,both are physically conscious of eachother,when situation demands they touch eachother and there is no holding back,they talk with their eyes and expressions very often. They are both protective about eachother and helpful ---so what is missing.They both need eachother. She wants to bear his child and he would like her to give him another child.That is the common subconscious desire they both have. The other aspects of their relationship is like Radha Krishna , in a way fulfilled , but because they live on earth in Kali Yug their relationship needs to get expressed biologically. That is how I sum it up.
