Everyone holds a mix of opinions, beliefs, and expectations on a myriad of subjects. When you give your attention to something, that Vibration becomes activated and comes to the forefront. And the more often you focus upon it, and cause it to come to the forefront, the more dominant it becomes.
You have the option of making a good-feeling aspect of another person dominant in your Vibration or of making a bad-feeling aspect dominant, and whatever aspect you regularly choose will become the Vibrational basis of your relationship. When your happiness becomes your highest priority, and so you deliberately keep active the best-feeling aspects of others, you will train your Vibrational frequency in such a way that they will not be able to rendezvous with you in any way that does not feel good when it happens.
The only way for anyone to be consistently happy is to understand that the feeling of happiness is simply about alignment with the Source within. When you are in your Vortex of Creation, you are lined up with all-that-you-have-become and with everything that you have asked for. There simply is no substitute for that alignment.
