@Love Eon,
Someone who has already made up their opinion and isn't interested in making a decision, is going to be hard to convince.
That said, I transitioned over by using DeKang NPort juice. Then I found Goodejuice house Blend menthol Tobacco. It's got the feeling I needed to vape and feel like I had an acceptable substitution.
The fruity and sweet flavors all tasted horrible to me for almost a month. So, if you want to give that a try, it's a worthwhile and inexpensive investment.
Also, I don't know what system you are using, but I started on a small eGo T setup, mostly because I felt a big device was too different and too bulky to carry out.
Now I rock my tank/provari and use mango, sweet tea, and all sorts of other flavors.
Be patient and supportive. If she's digging in her heels, circle around, Bob and Weave and try again in another week or two.
