Yes, it's common for people in a new and serious dating relationship to say "I love you" to one another. The timing of when individuals express these feelings can vary based on their personalities, cultural background, and the pace of their relationship. Some couples may feel comfortable saying "I love you" relatively early on if they have a strong connection and feel deeply for each other. Others may take more time to develop that level of emotional intimacy and may wait until they feel certain about their feelings.
It's essential to remember that every relationship is unique, and there is no one-size-fits-all rule for when to say "I love you." Some people may feel ready to express their love after a few weeks or months of dating, while others may need more time to feel confident in their emotions.
Communication is key in any relationship, especially when it comes to expressing feelings as significant as love. It's important to be honest with yourself and your partner about how you feel and to gauge their feelings as well. Understanding and respecting each other's emotional boundaries and readiness to say "I love you" will help ensure that the expression of love is authentic and well-timed.
