<human>: Give me the gist of the text in a nutshell

So, my boyfriend and I have been dating for seven months, and yesterday he asked me to marry him.  The question on my mind is not whether to say yes or not, but how long we should wait for everything. I'm heading off to a college about an hour away in September, but will be living mainly with him and travelling to school. 

My original thought was to announce to my parents in about a year from now, when he and I will both be 19, then have the wedding in the fall of 2016. However, the more I consider everything, the less I want to wait. If I could I would plan for a marriage late summer of next year. 

My question is, is en engagement at 7 months and a marriage at almost two years a decent amount of time to wait? Before I get any "You're simply too young to even be considering it." or "You don't know each other well enough." I know this is the man I want to marry. He has helped me through countless troubles, personal, family or with him. We make each other better people, and I can't imagine my life without him there for me. Our communication skills rival that of both mine and his parents, who have been happily married for 25+ years, and there is nothing that we cannot discuss. 

In my mind marrying at 19 will not be that much different than at 20.
<bot>: Is marrying my boyfriend, when both of us are 19 and will have been dating for two years too soon? What is the difference between marrying at 19 and 20?
