1. Do not cohabit with a man who has not married you. Do not live with your boyfriend in the same house. Even if he is your fiancé, do not live with him in the same house. You will look too cheap; people will be seeing you as a prostitute and a useless girl. A good name and reputation is better than anything in the world.
2. Do not be pregnant for your boyfriend. It is senseless. Avoid pregnancy if you are not married. Note that you can never use pregnancy to tie a man down. Your boyfriend will either deny the pregnancy or he will tell you to go and abort it. Pregnancy before marriage is not Godly and it is a shame to you and your family.
