Hoi EE,
(I'm married with child, please take with grain of salt)
Does she play StarFleet? If yes, do not wait the 4-6 months. Two weeks should do it, just to be polite. However, she is twenty years old, so be ready to move after 36 hours; life happens so quick at that age.
If she doesn't play SFC, maybe you could get two tickets for the next Club House Tour J'inn is doing as a first date idea. I understand that J'inn is a real softy when it comes to romance, an angle you could use should you need a discount.
If she survives the tour, you will know what to do; marry her. If she doesn't survive the tour, she will know what to do; devote herself to meditation, study, and mature into a capable, fine woman who starts a family with a man who has no idea what a Gorn is.
The groundskeeper at our building, also a published Zen Master, shared this set of fine words with my wife one sunny day, I hope the words provide a distraction for you when you find yourself "worked up" about your situation."You cannot have enough of the things you do not want."
Take care
