the appropriateness of saying "I like you" or "I love you" in a chat with your significant other depends on the nature and stage of your relationship, as well as the comfort level between you and your partner.
"I like you" is a more casual expression of affection and is often used in the early stages of a relationship when you are getting to know each other. It can convey a sense of interest and fondness without being too intense.
"I love you" is a more profound expression of emotions and is usually reserved for more committed relationships or when you are certain about your feelings for your partner. It carries a deeper emotional connection and commitment.
It's essential to be genuine and sincere in your expressions, and it's best to gauge your partner's feelings and comfort level before using either phrase. Communication is key in any relationship, so being open and honest about your emotions is important to maintain a healthy and happy connection.
