just for a better understanding

i never really got the purpose , are engagements done to get to know the person better or are there done with the intention of thats it we are getting married now? do people break engagements on idk because one day they realise the person does not look enough , or dont like their lifestyle etc

or does an engagement usually mean you have pretty much decided this is it, unless there are major differences in thinking etc?

Re: just for a better understanding

Usually it’s more of a “this is it”. But if major misunderstandings happen it’s easier broken then a nikkah.
