Do you see a difference between ‘Love you’ and ‘I love you’?
The five love languages are: Words of Affirmation, Acts of Service, Receiving Gifts, Quality Time, and Physical Touch. These are ways people tend to express and receive love. Everyone is different in how they give and receive the feeling of being loved.
Identify yours, tell your partner these are how you receive love and feel loved. Express how important it is to you. Expressions of love words are nice, but actions are the demonstrations of said love.
Love languages can also change through time or even based on the situation or mood, thus developing open communication is important.
