Would you be offended.....

YES! I'd think he was probably married and didn't want her to find out.

why care

Yes I would be offended

Yes. It's a very bad sign. Usually, it means the guy is married or engaged with the wedding planned, and he doesn't want anyone to know about you.

this can kind of happened to me, they knew about me, i just never met any of them until years after i'd ended things with the person

That's pretty hurtful. What's their reasoning? Or is this a general question..

Of course I would, otherwise I would reevaluate our relationship :)

no, everyone has their reasons for doing that.

What's the reason, give us some more background...

Yes, I would..it shows how much they care!

I don't think I would be

something seems fishy

I'd be single in a second

Yup. If it were me, I would say WTF. I don't know what a good reason for hiding it would be, unless there were a marriage involved. I would not want to be with someone who didn't tell others. I want him to be so happy to be with me that he told everyone! --DW

After a month without damned good reason.

After a year? Hell yeah I would be offended.

leave him. move on
