You are jovial in nature and will have good and reliable circle of friends in your life.
Astrology can give you the extent of matching and compatibility with the person you have in mind after the charts' analysis, however it cannot answer whether one marries a particular person.
The compatibility between you and Nikhil is quite good in most of the aspects such as, love, sexual relation, felicity, health. The only aspect where the matching level is lesser is that of temperament and mutual understanding.
Both of you need to work out your differences in these areas for a good and prosperous family life.
