The question is, how and when will you decide that you are with a wrong life partner? How do you come to that conclusion and how long that should affect you? Most of the problems arise when decisions are taken emotionally without assessing the other person.
If you know that the partner is not compatible, You will not marry them at all … right? You have seen some admirable and interesting things in the other person before you have proposed for marriage. Even in arranged marriages, the bride and groom will talk to each other before tying the knot and decide that they are compatible and then only the wedding takes place. Now let us say, if you come across some dark side of the life partner after getting married, there are many ways to solve the issues and if that does not work there is divorce.
