Couples too early cohabitation will be too early to understand each other, I think there are benefits and bad places. Nowadays, people fall in love unlike before, they often live together in advance to understand each other, in fact, some small details in life is particularly important. If you do not live with each other, there are some details you do not quite understand. For example, whether the other person has some bad habits in life that you can not tolerate, or the other person in life which good habits, you think is a plus, these are through cohabitation know.
I think it's good to cohabitate earlier. Because a lot of things you can only get to know each other thoroughly when you live together. Though some people would think that living together too early would ruin the freshness for the other person. But I think love has a shelf life, and after that all that's left is affection. Since love has a shelf life, why not find out in advance if this person is the one you want even after the shelf life? So looking to live together earlier can find each other's strengths and weaknesses, and then give you enough time to determine whether you are willing to accept his strengths and weaknesses.
Of course there are bad things about living together. Especially for girls who have lived together, the damage will be a little bit more. Because when two people live together, it is actually the woman who pays more. Maybe many girls are not willing to break up after knowing some of their boyfriend's shortcomings, then she will suffer more in the future. And nowadays this society is more malicious to women. Many people will have a discriminatory feeling towards girls who have lived with others.
Consolidating what I said above, I think it is a good thing for couples to live together too early. Of course there are bad things, but overall the good outweighs the bad. Because two people get along is not a momentary together, really want to be together or to think about the long term. Earlier cohabitation can find out whether the other side really meet your own requirements for the other half, but also can more quickly enhance the relationship.
