if you find out that your wife had multiple relationships or boyfriends , what will you do ?

this Modern time relationships are very common . And Indian girls have so many choices and many boys chase them as well so they are likely to have a boyfriend very easily.

I am 27 and , I have seen many of my girl classmates are married now, and I know how wild they were (in terms of relationship and fantasies) and they married to the simplest guys and I don't think any girl will tell honestly about her past (like 4,5 boyfriends and all) to her future husband. So I feel bad for husband , and I also fear for my self . So what will you do if this happens with you and how can one know these things prior
