Don’t complain about every small thing that irritates you. Be more accepting and let things be. Your partner is a different human being, so let them be that. Accepting the differences makes the similarities more enjoyable

Building open, clear and safe channels of communication in your relationship not only removes the stress and distance of guesswork, they also bring in fulfilment, empathy and a real chance of growth. Remember, no matter how well you know your partner, you can't read their mind.
