3. You’re able to communicate: Communication is key in any good relationship, but you can’t be completely open with your partner if you don’t have the traits mentioned above. Communicating with your love is all about commitment and trust. If you’re able to commit to and trust your sweetheart, you can be open with each other and explore each other’s feelings, needs, and desires. Understanding and appreciating what your honey has to say, and being able to say what you want without fear of them running out is a sure sign that you can say “I love you” to them and mean it.
