Hi, don't know. Personally happy with arranged marriage. All you need is love between the couples either way.
It does not matter arranged or love marriage. More love marriages end up as failure because of over expectations. It is foolish to think someone can know everything about other person in love marriage. Our judgements are never 100% accurate. After all we are only human. It depends on the personality and willingness of a person to sacrifice things for their spouse that makes good marriage.
In the intial few years, the amount of time you spent getting to know each other prior to marriage matters. A LOT. In that sense, a love marriage or an arranged match where the two partners are in constant touch prior to marriage is definitely a better choice. So love or arranged, choose wisely. It's hard to undo the choice of spouse. Take all the time in the world to get to know what you are getting into.
In a love marriage, I feel, the understanding between the couple is better.. Just my opinion.. I had a love cum arranged kinda marriage, met through common friends, discussed our values and thoughts and then introduced our parents to each other.. I feel a love marriage is better cos you are more in charge of the decision, cos irrespective of who decides ultimately only you have to face the consequences- good or bad..
