I'm thinking of leaving my chick, WHY

i will tell you
for sometime now ive been taking this her act of selfishness. i've found out that she prefers her family 100% to me. for example if i ask he to do something for me and it also happen one of her aunts somewhere is having a party or doing something, she will always go for that her aunts event and place me second (ALWAY) which is something i don't do to her. sometimes she may even forget me ontil i talk and talk and talk, this was not what i wanted from the beginning

, i know you can't forget your family because of a man or a woman, what i feel is that they sholud be a balance between the two parties and not putting one ahead of the other 100% if they is real LOVE.
i love this girl very much, the relationship is going to 3 years now, i have never asked for sex and thats just because of how i feel.
want to wait till marriage. but now i'm thinking of moving on. i have told her time without number about this act of hers, she will always say i'm sorry and do the same thing again.

i feel so sad because i have put everything in this relationship, hoping for a perfect ending.

please my brother and sisters What should i do?
