i got engaged twice, first one was quite weird, i knew the girl and the family since very long, but the girl was least interested to be in contact with me. always felt something is not quite right when i managed to speak to her couple of times. then i stopped trying and stayed out of contact for rest of the engaged period and eventually walked out of it.
all along she had an affair, agreed to engagement just being good girl in the family, dont understand bit cause she was consulted before putting proposal to her parents only after she didnt raised any concern, it cant be shyness as she was a good friend of my sister.
just after few months i walked out of the engagement, she just went for civil marriage with the guy.
so if it was a guick mangni and bhia, i would have been trouble. I think its better to end an engagement than a divorce. however family stuff can put extra burden on this fragile relationship of engagement.
personally i would have a nice time before the formalities of a wedded life, specially for those guys who waited for only one and can enjoy some dinners and outing before married life, married life cant compare to this one at all.
