Just wanna ask one simple question..
What do u want to do filing a complaint!!
If he is really not interested in you, you should consider yourself lucky that he is showing it before marriage. If you wanna make your life hell, you could put a gun, i.e complaint, against his head and you can make him marry you. But.. just think, will you guys be happy with this kind of marriage.
If you want to file a complaint to get married, forget it.. he will never be able to get over this even if you guys get married. If you want to teach him a lesson, yes you could very well do it by ruining the best part of your life i.e youth by filing a complaint.
Max thing court can do is to punish him under some section, nothing more than that. They definitely cant force him to marry you.
--- If you still want to file a complaint, -- many women are filing rape i.e 376 and i.e 417 breach of promise to marry..
