It’s good to remind your partner about your feelings. You can do it verbally, or alternating with small written messages filled with warmth, love and passion.
Leave a gentle note in which you sincerely share your emotions: “I get excited every time I remember your lips”, “When you are joking, I want to drag you to bed”. Write about the nice things you’ve noticed, the shared experiences, the unexpected confessions.
If you are far away from each other, create a messenger group chat for just the two of you and share your desires and thoughts. Try to write regularly: this will show how valuable this relationship is to you.
