Many artists have high emotional intelligence, much higher than the less creative part of the population. That’s why artists feel things differently and may show different behavioral patterns that seem “weird” to the rest of the world.
That artistic sensitivity might be hard to understand for someone who sees the world with “normal eyes.” Nevertheless, you should try to make your partner understand that you are feeling things more deeply. Therefore, you might feel overwhelmed, sad, or depressed, where other people have no problem to remain level-headed.
At the end of the day, I believe it’s difficult for someone to feel things the same way you do, if they are not naturally wired that way. For a long and happy relationship, though, it’s important to have a partner who genuinely sees you and accepts you the way you are. So, choose someone whose love affects your creativity positively!
