Well you really can't make your parents get back together after there divorced. You shouldn't worrying about that. If its fate then they will get back together on their own... Just show your parents that you will always love them no matter what <3 hoped that help :)
Yea but only if both her parents and his parents say it is ok for them to be together. If one of their parents do not agree to let them be together then those parents have a rite to call the police if they have sex or something in that matter.
