Be cautious What2do as even if you have a lovely visit (and I really hope you do), the long distance relationship is a tricky one. I speak from my son’s experience of a 3 year relationship with a very nice young woman from America. They saw each other every four months or so, taking it in turns to visit and always had a great time and seemed more and more in love. They talked for hours, emailed and sent little gifts - it was lovely to see him so happy.
Then, after a lot of thought, he moved over to be with her and over about six months, it became clear that although they loved each other’s company on visits and holidays, they found they had no chance on a day-to-day basis as when working, shopping for groceries, dealing with relatives and the ordinary pressures of daily life, it just didn’t work.
It became extremely strained and difficult, and they had very different expectations of life, yet they had spent hundreds of hours chatting and had both invested such a lot in the relationship.
Whilst I’m not by any means saying all long distance relationships are doomed in the day-to-day, I just want to advise caution. IF things go well, be wiser than my son, make sure you have the chance to see her “ordinary” life, not just her “holiday mood” before you commit.
As to your dentures... if they matter, she’s pretty shallow and you’re wasting your time!
Good luck.
