Your interactions are so smooth, you almost don't notice how smooth they are! You notice that you feel really natural together, as if you've been friends forever, even from the time you first met. There is some deep level of commonality you share that is beneficial for both of you.
Your lover gives you a lot of emotional support, which is wonderful -- but better yet, they somehow give expression to your emotional life, including the more difficult emotions that could come up when life gets rough, as it inevitably does from time to time. You talk over your feelings and they intuit how you're feeling or handling things, and then they seamlessly glide into place wherever they're needed -- a cheerleader for your accomplishments; a shoulder to cry on when you're feeling blue. This doesn't just go one way; you provide this support for each other, so you both feel taken care of and well understood. This influence has a lot of long-term potential for this reason. You're also quite creative together; you could launch a project as a team, or you could just enjoy a deep and diverse bond that you share and have fun with! Your lover is able to help you through hard times due to this influence; they help you handle any heavy or otherwise difficult feelings, and process them in a healthy way.
