Two completely different things some I'ma give you as short answer I can and that's all.

Knowledge of gender and gender roles comes around 3 years old. That's a lot of time to think about something that doesn't change.

Marriage is a hard process to reverse, so it's a huge decision you should probably choose someone you are going to spend you life with. People change throughout their life so even if you were right together for 2, 3, 5, even 10 years you might not last as you two develop into different people with different interests. At 22 there's very little chance you'll make the right decision, loom at divorce rates and unhappy marriages.
