went through the same thing.
Andrea had that engagement ring when she was 16 and nothing could thwart this thing.
but.

so far, knock wood, it has been wonderful.
they have a little boy who's going to be 2 on Saturday and their relationship is strong, so far.
my only worries are what's going to happen when they're 29-30 and they realize they had all the time in the world and missed out on most of their young lives.
