the internet can be a powerful tool. you can look up ANYONE if you know where they are from; first and last name. anything from social network sites, emails, blogs they have will come up.
i know its tough...but if you want to see how she looks like that's your best bet. i am not saying to snoop INTO your husbands stuff. but the internet is public. (keep that in mind) i only say to do this bc it will give you some what of a piece of mind..BUT beware it can bring up stuff. so if you aren't prepared to do deal with those demons i suggest NOT to do it. its tough trying to trust someone. but if you want your marriage to work. you will have to do that.
