If your boyfriend sends you a black heart emoji with the text "I love you," it's a good sign that he is expressing his love and affection for you. In response, you can reciprocate his feelings by sending a heart emoji of your own, such as a red heart ❤️, a pink heart ?, or even a black heart ? if that's your preferred color. You can also express your love and appreciation with a sweet message, such as "I love you too," "You mean everything to me," or "You're the best thing that's ever happened to me." Ultimately, the most important thing is to respond in a way that feels authentic and true to your feelings.
