You will never be perfect, nor can you expect this from a partner. There will always be issues that come up and you can either learn to treat them as you would any other obstacle or you can hide them until they balloon into a huge problem.
Make a commitment to hold a weekly check-in in which either of you can bring up any issues you have on your chest. Communicating problems with the idea of tackling them as soon as they come up helps you establish a strong foundation.
