When it comes to describing a close and personal relationship with someone, the phrase "intimate with" might feel a bit too specific or even inappropriate at times. Luckily, there are plenty of synonyms and alternative ways to express this concept. Some options might include "close with," "familiar with," "well-acquainted with," "connected to," "emotionally involved with," or simply "knowing someone well." Depending on the context or tone of your writing or conversation, you might find that one of these phrases fits better than others, but all can convey a sense of deep understanding and connection with another person.
