ignoring all the ridiculous people who are fighting, my advice would at first glance be kidnap her. as i scrolled up and read everyones comments i put the finishing details on the plan. until she is eighteen, keep restricted contact. an occasional email. let her know you just want to make sure she is doing okay. talk about semi-superficial stuff, or at least not about your relationship. when she turns eighteen or shortly afterward, see if anything changes in her life, and if she attempts to contact you or changes how she writes to you, if she still does. if so, go from there. if not, arrange to bump into her in a public place and act friendly. play it by ear, and try to get her to spend time with you. if opprtunitypresents itself, kiss her passionately and tell her that if she wants, you are willing to run away with her right now...leave her family behind and restart the life you would have had together. i do not think it is right to just move on and give it up, especially since she is obviously not in a good situation. if she is actually being physically abused, consider the pros and cons of turning her father in as an abusive parent. maybe not such a good thing, cops make things worse, but if you can get her out of that situation...
yeah man, you gotta prove to her family that you arnt a grengo and marry her all properly. that would be cool (although im not sure that im helping). that way she can still be with you and have her family....because if you tear a woman apart from her family (in most cases, not sure bout this one) it wont last.
the problem with that is, to get married to a muslim you also need to be a muslim or convert by the waterfall had good advise although i wouldnt call it kidnapping, lol i'd call it rescuing, if your sure she really wants to be with you too, be desceite in all communications, but let her know when the time is right you'll be ready..you can either leave it to her to decide when the time is right, & wait on standby for the call to action, or secretly arrange things ahead of time keep in mind that it will be a hard thing for her, so be patient & understanding to the guys arguing, wiz, i'm surprized youd say just give up, its hopeless.. & the other guy suggessting he buy her? sure that may be the norm in arab countries, but doesnt make it right or acceptsble here & she would be happier i think if she broke away from her family...then if they sold her like property
