Well, you have to be careful about it.,dont just jump into consclusions.. and  i am just wondering how you get your proof if you are not here... I hope you are not relying to hearsays :(

Better to have a strong, valid and factual proof before going into such actions, or you might end up ruining your marriage once you come to know that he is really telling you the truth.

You can contact the CID for such reports, (sorry, i dont have their number but you can google it)!

Goodluck
