if he did ask you to marry him please tell me that you'd say no. for god's sake you are only 19!!
Happy birthday Kitty! I agree with Jared's post - in spite of the fact that you say you are a very mature 19 year old.
Maybe I missed it - but how old is your boyfriend? How mature is he?
Here is where I am coming from:
I got married at 19 (wifey was 18). We were a lot more mature than most 19 year olds (at least we thought so) and because we were totally immersed in the borg, getting married was a prerequisite to sex!
Almost 32 years later we are still happily married - and have survived some major crisis over the years. Unfortunately, for most teen marriages the odds are NOT in your favor long term.
There is so much life that you have not experienced. Your view of what's important is going to change a lot, and what you like in your boy friend now, MAY become annoying later on. Have seen so many young marriages break up because one or the other partner matures faster - OR because you have not sowed enough "wild oats" before marriage - the temptation to do so takes over when the "initial thrill" starts to subside.
Have either of you considered college? How about getting education/career etc going first? Put off having kids until those items are securely in place - otherwise you may never get the chance to realize your full potential.
How about a prenuptial agreement and waiting until you are in your mid 20's? You may not have much in the way of money and assets now, but that WILL change. If you break up or get divorced that piece of paper could save you or him $$$$$ and a lot of pain.
You will probably ignore my advice (I ignored my dad's - but fortunately things worked out for us! ) but I hope you will speak with family or friends who have some more life experience and seriously consider what they have to say.
I have no idea what your boyfriend may surprise you with, but I wish you a happy life.
