Well, your decision seems to be the sensible one as you don't want to marry her right now because you don't want to make her live uncomfortable with you when you are unsettled, this shows your level of maturity, apart from it the second biggest thing that you are to counter is that you have two unmarried elder brothers who are to get married first for you to get married, but for now I would say, you may go to her Mama and Mami and request them to give you some time till you settle as you love her and want to marry her in future. If you really do love the girl, I think you should take a step forward and talk to her guardians, also I would suggest you to first initiate a talk about your marriage at your home and introduce your love as your friend at your home, let your parents get acquainted with the girl and if they started liking her after meeting her, then half your battle is won, because your parents may then straight forward have a talk to her guardians, which may ease this matter a bit, because elders talk gives much more importance in this cases than the talk of the youngsters.
