Why don’t you define what arranged marriage is?
It really doesn’t matter if one ‘saw other’ or both ‘saw’ each other somewhere, and sent the family or family found the girl and then family let each other met before marriage.
It is arranged marriage. Not third category.
Love marriage or pasand ki shaadi means they met independently or secretly had affair, spent time for a while, and then either with or without family involvement/approval got married.
By the way, both marriages can be called ‘pasand ki shaadi’. Long gone the days when they see each other on wedding night the first time.
Now forced or coerced marriage is different. one does not really likes the other but for some weird reasons or unusual circumstances (watta satta, rape victim, one night stand with pregnancy as a result) they have to get married. Not a good thing but it does work out in some cases.
