What are the responsibilities being in a relationship?

First of all a person, a couple, should always know that a relationship takes two people to be one. Having a good communication between one another, wanting to solve predicaments among the relationship, caring to be there for one another whenever needed, not cheating on the other, not lieing to the other, being as truthful about your feelings to each other, doing what you say you will do to be with this person in your life. Giving love to the person you say you love, also known as your significant other. Know what you want in and out of the relationship and be honest about this with the person from the very beginning. Treat each other with respect, know you may disagree at times, but also know that it takes time to grow and that it will get hard at times. Do not give up so easily, do what you say you will do. The major things for a relationship are trust, friendship, love, strength to stay thru whatever, time. Definitely put time into a relationship, because what you put in is what you are going to get out.
