Shame of my previous live - to lie or not to lie?

Islam provides a code of manners for male/female interaction outside the home. 

D. When meeting and greeting: Men shake hands and hug only other men. Women shake hands and hug only other women. (Unless they are married to each other, of course.)

E.  Men and women who are not married to each other never touch

Assalamu 'alaykum Meryema

 Welcome to the true religion. You are really blessed by the almighty to get the real wisdom for knowing the correct path for this life and afterwards.

But as a Muslima we must understood one thing that Islam is not allowing any male/female relationships before and outside the marriage. �Boyfriend/Girlfriend/lovers� these are not permitted in our Islamic life. So as true believers we should not encourage these things. Any relationship outside the marriage is a sin and adultery as per our religion. It is clear that we should not start a relationship with a male before the wedlock. So my point is that, you should avoid having contact with your male friend simply because it is not allowed. The life before you enter Islam is totally different than the life after you became a good Muslima.

According to Islam, there is nothing called as love marriage

There is no concept of courtship in Islam as it is practiced in the West. There is no dating or living in de facto relationship or trying each other out before committing to each other. There is to be no physical relationship whatsoever before marriage.
