Dear sir, I'm recently married man. My wife has got stitches across the stomach (before our marriage itself) as in case of Caesarean. But she refuse my allegation and says it was just an cyst operation.

As far as my knowledge is concerned, a cyst operation is done on either right/left side of stomach NOT across.

So am I right in doubting her character?

What has this got to do with her character? And why does this scar matter to you. It is kind of late to "doubt her character". Is it not ? If you think she delivered a baby by caesarean, where is the baby?

This should have been resolved before marriage my friend. More information please, since you could very well be all wrong, but are you questioning her character because you expected her to be a virgin and now you don't think she is? Is this an arranged marriage or a love marriage? How long did you date? How long had you known her before this marriage?

How long have you been married?
