Why Would A Girl Date An Older Man But A Guy can't Date An Older Woman?

Hey peeps around, I was just thinking maybe yah all can help with this, I am currently in love with someone that is 6 years older than me and to be precise am 21 while she is 27 and i really love her and she loves me too and i am also afraid to say that she loved me more than i love her and i know everything about her and she does the same but the problem is that her families her telling her to get married and she said she want to wait for me till i finish my school so we could both get married but am scared about everything , I don't know what to do as am still in my 100 level while she is already working in one of the biggest insurance companies, Do you think i can go ahead or i should just quit before its too late because she said if she eventually gets pregnant for me she will NEVER abort it so i am SCARED OHOHOHOHOHOH, Though she is nice and anytime i tell her somethings she listen and doesnt do as if she is the oldest but still yet i still give her that respect that she is older than me, Please advice
