is 2 years too soon to get engaded

Ever meet someone you know you can't live without. I was in a 5 year relationship before the one I'm in and she cheated on me and we are done. I met someone knew that is far different from what I've dated in the best way possible and honestly I can't take another second that I don't have a ring on it cause me likey in fact me love it a lot. I've gone ring shopping and just so you know where her mindset is she told me one day after sex if you don't get down on one knee and marry me then I will do it for you. what do you guys think?
