I commend you search for information on this, but if your doing it only to please your wife, chances are that your conclusions won't be satisfactory to either of you. If you want, search for your own set of beleifs in your own time, but don't do it simply to please someone else. I've seen this happen and I'm convinced it never works.
On a side note, if your wife is truly a beleiving Christian she won't leave you over this. I know that the divorce rates for Christians are high right now, but there is no getting around that the Bible says God hates divorce.
