Your courtship might be a fairy-tale romance and marriage is the next thing that is on your mind. But do you think you have spent enough time with your would-be partner or know him/her well enough to stay with them forever? If you have the slightest doubt, then hold on because before you realise it you may not even like to be in the same room as that person. The latest example being of Kim Kardashian and Kris Humphery's larger than life wedding. The couple tied the knot after dating for less than a year in a lavish ceremony but their marriage was a 'big mistake' as Kim has been heard quoting. This is not the first time such a thing has happened and there is a awfully long list of famous people who married rather impulsively. Says psychiatrist, Anjali Chabria, "More than time it is about how realistic you are about the relationship. They do not see the warning signs even if they are right in front of them and just hurry into tying the knot." An international daily quotes that there is a brain chemical that is responsible for triggering the feeling of love. The chemical called Dopamine makes you feel overly positive which might make you overlook the fact that your union may not last that long. This positive feeling wears off in about six months and that is when fights start happening and the generally cute habits become irritating. A lot of times people do not realise that their future plans do not match and issues start cropping up later in the relation, according to marriage counsellar Riddhi Patel. "There have to be common goals with respect to children, money, work etc. And for all this you need to spend time with each other before getting married," she says.
