Diana,
This is wonderful news!!! I know you are concerned about her being so young, and I can relate soooo much. My daughter got engaged in high school too, and she got married in June after she graduated from HS in May. I wasn't upset, horrified, but not really upset LOL! I was however, VERY concerned that she was too young, hadn't had enough experiences, etc etc. My only foot stomping fit was about college. As you know I have my PhD and I just couldn't fathom that she wouldn't be a college graduate. She poo pooed me and said that OF COURSE SHE WAS GOING TO COLLEGE. I'd told her I would pay her tuition and books, so there was no reason not to go. Her hubby had a good job and she only needed to work part time. All went well till she got pregnant in the middle of her freshman year.
But true to her word, she had Abigail in Sept, took that semester off from school and started back part time that next spring. It took her 7 years, but she did it! YAY!!!
They have been married 14 years and I can't imagine having any other son-in-law. He is just the absolute BERRIES! Love that kid!
