Live in relationships are all the craze these days in most of the countries from USA to Brazil, UK to Philippines, India to South Africa. The question at the time of entering into the live in relationship and even when you are a few weeks, months or years into it is always whether you should get married or continue living like a couple who share life but is distant from the lifelong bond.
At times this question can eat up into the relationship, creating trouble at random times, if one of the partners wants to marry and the other is not willing.
