18 and engaged...maybe?😁

I am so excited and anxious! I will start off with a little bit about me and my SO first. We have been dating since August, met in July and have yet to spend 24 hours apart. Everything about our relationship has been rushed, and I wouldn't say that's a bad thing! We moved in together after just one month of dating, but so far it has been amazing and I love waking up and going to bed next to him every day. We have been talking marriage for a few months now. Last week we went ring shopping! To my surprise, we both fell in love with my dream ring and he had me go off on my own while he spoke with the jewler salesman. Later that night I finally got it out of him that he had put my ring on the stores Layaway and put some money down on it! YAY!!!! When talking more about the engagement he told me that it would be sooner than later and that it would be this year! I was like a giddy little puppy at this point! He just said after he paid off the band (about $1300) he would be able to get the center diamond (about $6000) financed and propose!! He's dropped a few more hints about it when I've asked. The latest one was about how we are going on Vacation with my family at the end of May and that I would just have to wait a few more months after that! I am now assuming that he is going to purpose on our 1 year anniversary date (August 28th) What does everyone else think? Am I crazy and expecting it too soon? He told me it would happen sooner than later.... I also wanted to get peoples input on our ages? I am turning 19 next month while my SO will be 21 in September. Are we too young and rushing things? We both are in love and feel the timing is right, but I want to hear some opinions!
