In Spanish, you can say ‘I care about you’ by using the phrase ‘Me importas’.
This expression conveys that someone is important to you and that you have feelings of concern or affection for them. The verb ‘importar’ directly translates to ‘to matter’ or ‘to be important.’ Therefore, when you say ‘Me importas,’ you are essentially saying ‘You matter to me.’
If you want to express a deeper sense of care, you might also say ‘Me preocupas’, which translates to ‘I worry about you.’ This denotes a stronger emotional connection and concern for someone’s well-being.
