Love Language/Physical Touch

My son, 15-year-old Landon, used to snuggle up on the couch with me when we'd watch a movie, hug me in greeting, and even asked me to tuck him in at night. Three years ago this stopped abruptly. Now I'm lucky if I get a high-five or fist bump and if I want a hug I have to chase him down. He's 5'9; I'm 5'4. The chase is futile. I understand that it is natural for a son to push away his mother, but there have been moments in the last three years that I mourned the hugs of my son and wished I hadn't taken them for granted. But, I've learned that Landon's love language is not physical touch, it's quality time. He likes to be heard and feel that his words are valued. I had to flip the switch and speak his language in order to show him my love, instead of forcing my love language on him.
