21 is when you are growing and becoming more of the authentic you. Do not, under any circumstances, let others choose your path for you. They are hurrying you towards something they feel they need, not something you need. I have no idea why anyone would get married or in a serious relationship in their twenties since that is when you need to be figuring out you. If you really look at their relationships, you are likely to see a bunch of codependent people. No one can make you happy except for you. The fact that you get this and they don’t is a reflection of your maturity and your stability.
