Hi,
Daily I am chating with my fiancé. I am loving her sincerely and deeply recently I came to know she had an affair with one guy our marriage is fixed after3 months. Now I can't forget about this affair.and I cannot talk to her as before I am very sad. Is better to avoid this case?is my life will be spoil?

Did she lie to you about her previous sexual history? If you cannot "live" with knowledge of this affair the time to cancel the wedding is now - your sadness and upset are not going to vanish simply because you get married.

If you are going to marry this person you are going to have to be able to talk to her openly and freely about this and (probably) many other things.

Are you saying that she had an affair while you two were together or before you two met?

If it was before you met then it's not an affair, it's called a relationship and we all have them in our past.

Talk to her about this. If you can't come to terms with her past then you don't have a future.

I can't clearly understand weather she had this affair before you two got enggaged or after that?

Whatever is the case you got to understand that its imp to talk to her and tell her what you feel about it right now, because now is the time for you as you two are still not married and your options are still open but if you marry her with this feeling its going to be difficult for both of you and that is only going to further complicate the matter soi think you have to decide weather you love her so much that you can seriously put all this behind and live a happy life together and if not then you should think before getting married to her!
