No, you're not bilingual. But you do have a love language that if spoken to you can make you feel loved. And if you speak your partners love language to them will make them feel loved. Most of the time the love languages are not the same.
So what is a love language? It's a way of showing or receiving love and gratitude that has the most impact. The languages are:
1. Words of Affirmation. Thank you, encouragement and positive words make you feel appreciated and loved. Insults can make you feel shattered.
2. Acts of Service. Having things done for you speaks volumes. Small is fine too, but having it done for you is huge.
3. Affection. You like to hug and be hugged. But also pats, touches and holding hands make you feel cared for and loved.
4. Quality Time. Full, undivided attention. Being with each other. These will make you feel special.
5. Gifts. You like gifts that say they really understand you - not a gift for a gift-sake. They represent love and are treasured.
So what language are you and what language is your partner? You can take the test here and find out. And Gary Chapman's book "The 5 Love Languages: The Secret to Love that Lasts" can be bought on Amazon here.
