Jan from TamThey brought in that new UK law making marriage illegal until 18 because muslim girls were being forced to wed abroad by their famillies against their will. The problem was that these girls being 16 were still minors and as such in their parents care so they could insist the girl go abroad and then once there were forced to wed. Hence they changed the legal age of marriage to 18 so the girls could leave home if they suspected they were going to be forced to wed and at 16 made such a marriage illegal (and no use to the groom since the wedding is to obtain citizenship for him and that would be null and void).
Sadly that law affects western girls in your position Jan. I do think the legal age of consent should be 18 (with a Romeo and Juliette 16 to under 21 clause in place)
