Thanx to all who gave me good advices. However, pregnancy will not be an option to me

I am a south african. I met a nigerian guy. He is a christian,well mannered,full of respect and love and fit everything I look for from a man. We have been inlove for a year. However, some of my family members are against it just because his from nigeria. I really do love him and he feels the same way. Now they even hate me because of him. Any advice?
