I am 19, female. my mother is 56. father is 57. do i need to marry earlier??

my mother has been trying to train me to be more matured (as I am the youngest, kind a spoil), to do house chores and many thingswhile my father, who has always been proud of me, are giving me rules for every single penny he would give. and if I want more, I have to work with him (like marking his students test papers)the problem is my mother. she has been giving hints for me to marry. I have no one as a husband candidates but she tell me if I want to marry, she has one man in her mind. I ask her, why so early? she tell me she needs rests and time for herself (she has always been busy raising 8 child's and working as a high school teacher, for almost 25 years. she work damn hard). I understand that.then, she told me that marrying at my age could bring to mental depression (if I am not really ready) and 'that' things between a couple itself could be a trouble. I understand that because I am myself not meeting any boys (because I don't want to).actually, I'm planning to marry when I was 24-26. but... that is 5-7 years of waiting for my old and exhausted parents. and, I'm thinking of marrying someone who is 4-7 years older than me. please give me some suggestions/comments/advice. we all know marriage is not a game.
