my mom used to tell me there are things that i am going to find out when i start dating someone: you have to work at it together. and you have to love two things. you have to love 

1. each other

2. your relationship

what she means by the last one is there may be times that you fight, and sometimes you and your partner will not even like each other. but those are the times you have to love your relationship. it is like a third party. look at those photos you took together. look at any memories you have made with each other. and if you believe in those memories, they will always pull you back together.
