Unreasonable

This was my thought, too. Why had she not already known? What led her to believe you were a virgin, OP? Obviously she feels strongly about waiting till marriage. It's not everyone's cup of tea, but you have to respect people and their beliefs. Boy, wouldn't it be a kicker if she had slept with men before too, though?

Maybe this other girl is a best friend, a sister or just someone very close to her. I don't know but there is always another side to the story. This fml does makes her sound a tad crazy though so OP could've just dodged a bullet.

I totally agree with you! Some people are just crazy but there are always two sides to a story and maybe it was a huge deal for OPs fiance finding out. Especially if OP maybe denied being with someone else before her, I can understand her over-reacting. Maybe I understand because I totally freak out if I find out someone lied to me, especially over something like this, which is more than just a little white lie to some people. Relationships (and eventually marriage) is built on trust, and if you feel you can't trust your partner because of their lies, even if it is just one, then maybe it's good to 'postpone' the wedding until both parties can find a solution and figure out if they can re-build that trust in each other again. Otherwise it'll just be a marriage from hell with both parties second guessing each other the whole time

If she merely assumed he'd never been with anyone, then it's her own fault. If she asked and he lied, then it's HIS fault. If them both being virgins is THAT important to her, then it's something she should have brought up long before even being engaged, not after being engaged. Also, unless you have kids, STI's, a restraining order on someone, etc, I don't see why you'd need to bring up past relationships in a current one. What you did with someone before you met someone else seems rather irrelevant, but that's just my opinion. Again, these are individual things that should be discussed and not assumed, before things get serious.

It's just a way of getting to know someone...you know and accept the best and worst stuff they've done, understand their past...it's nice to have no secrets. It shows how much you trust each other.

*shrug* To me there's a difference between keeping secrets and existing before you're with someone. Like I said, some people like (and want to) share everything, and that's cool. It's a matter of compatibility. Personally I'd feel weird being with someone who wanted to sit down (figuratively) and talk about everyone I'd ever dated or slept with. It just seems bizarre to me. Again though, that's a total compatibility issue. If you're with someone who believes in total disclosure and that's not you, obviously it's going to cause issues, and that's definitely something that needs to come up looooong before you get to the being engaged stage.

I agree. If her fiancée always told her he was a virgin then right before the wedding said he was with someone else then I can understand her being upset. Especially if she was stating a virgin before getting married.

exactly - if OP lied about being a virgin for example, that IS a huge deal, especially if she didn't use protection and didn't get tested and was a virgin herself or for religious reasons, etc. Needs more info.

I disagree sometimes people dont want to be with someone if they have been with a lot of people or even just one person besides them, sometimes people want to be someones first and last is that so outlandish? It can be a really big deal to someone. It was to me, call me crazy but I dont want to end up with someone who has been around the block one too many times, people dont want to be compared to other partners and this can develop into feelings of inadequacy in multiple ways and levels. I dont really have to worry about this aspect but I got lucky.
