Ready for a boyfriend?

I talked to my mother and my sister the other day and they told me about my other sister Eme She is going to be 18 years old this March and I guess it is okay for her to have a boyfriend. They said that she have an american boyfriend right now and this guy own two beach resorts in the Philippines. Well, I am so happy for them but I am hoping that their relationship would work out good. I am happy for my sister I am just hoping that God will bless her life.
