Engaged at 19?

Samantha

My boyfriend and I have been officially dating for 2 years but the two years prior, we’ve been off and on. I’m very close with his family and right now, him and I are going through a rough patch. But being so close with his family, they have informed me that he still plans on proposing this coming December. Do you guys think 19 is too young of an age to get engaged? He’ll be 20 in may and I just turned 19 earlier this month. Another thing is that, the fact that he’s in the army, he lives farther away and he was planning on proposing when him and I went to visit his family this Christmas, but I feel that it’s important to have my family there to witness it as all. What’re y’alls thoughts?
