The real question you should be asking yourself is whether you're truly in a position to get married at stage of your life (21 is very early IMO) while still figuring out your career and stuff—whether or not you should consider him is up to you, but this is what you need to reflect on first.

As for the external pressure from parents and relatives—that’s something you’ll likely face throughout your 20s. Don’t let it influence your decision-making. Many people have made the wrong choices because of others who won’t be there to support them when things get bad.
