Right now she probably views Mormonism as just another Christian church (albeit with some quirks,) and perhaps as a viable way to raise a family.
Richard Packham wrote this as warning to church investigators. You might find it useful. Since the young woman is probably less concerned with doctrine at this point, skipping down to "Your Life as a Mormon" might be more to the point.http://packham.n4m.org/tract.htm
As a nevermo, the points that would get through to me the most would be the huge and unrelenting time and financial commitment, the intrusiveness of bishop interviews (including questions about masturbation,) the lack of privacy, i.e constant church visits, phone calls, and general nosiness, the paucity of charity work compared to the money raked in, and more than anything, the possibility of your own family members (especially children and grandchildren) shunning you if you decide to leave down the road. She could even face the possibility of being shut out of her own child's wedding one day.
And, if her future husband insisted on being married in the temple, HER parents would be shut out. Ask her, what church would ask this of someone? Does that seem right to her? Would she really be willing to shut her parents, grandparents, siblings, aunts and uncles, nieces and nephews, out of her own wedding ceremony?
The Mormon church tries to reel women in with the promise of "forever families." However, the belief of being reunited with your family in heaven is common to virtually all Christian denominations. It is nothing special.
But the biggest thing (and IMO a difficult concept to get through to a young woman in love,) is why should she be the one to bend her life to accommodate her spouse? Why wouldn't he consider her own views on religion, when it comes to forming a family? Why does it have to be all about him? Why doesn't she count?
