Telling or not telling doesn’t really matters I guess. Love is the whole human thing, meaning all feelings, emotions, body language along with joy and laughter. And I think when this happens it becomes all about mutual understanding and acknowledgment.
Bring your best to the table, start doing what you want to experience in a romantic relationship and yes pay good attention to your health and fitness. Go out on a travel trip together or join some dance classes or anything that could be fun and spend more and more time together.
