I'm thinking they were broken engagements rather than rejected proposals. If you know someone well enough to propose, you generally know the answer you're going to get. Not that there's anything wrong with that -- plenty of people have ex-fiance(e)s these days.
You need to re-read his post. But still, 5 Ex-fiances? That's even much worse than having 5 guys propose (at different times) and turn them down.
To the OP, sorry to rain on your parade. Be more careful what you post next time.
