No you wouldn't make a marital mistake i can assure you of that and it all start with that believe. You have to believe you won't make a mistake this time. Don't let your bad experience of men influence your general feeling about men badly that you become scared and make a mistake. If you believe in God, this is the right time to seek his face toward choosing a life partner, though i am not a too religious person but i have to give you this advice since you are not sure of which way to go.

Take your time and don't get influence by people commenting and expecting you to get married when they are still struggling with the one they got into.
