Have open communication, trust, and respect.

I personally think it's difficult to have a relationship without those three components.

Be the person we want to be without fear of judgment by the other. Include them in our thought processes and try to find a mode of communication that is agreeable to both. Talk about what we want the structure of the relationship to be (how much together time, how much alone time). Always be thinking and talking about the future, and what we want it to be, while also enjoying the present.

I think respect is most important. When you respect someone, you are honest with them, care for them, want to spend time with them, treat them the way you want to be treated, support them, accept them, communicate with them, and listen to them.

I think forgiveness is second most important. Knowing that nobody is perfect and that every relationship has a problem sometimes- and being willing to forgive and let go of the mistakes that each other make and forgive the little things that they do to drive you crazy.

Finally, I hear so often people who go into relationships and see things about the person that they want to/try to change. I think that's really sad. To me, true love isn't trying to change who you're with and make them better looking or more responsible or whatever. It's loving them for who they are and not wanting them to change that even though they are not prefect.
