YES! THIS! I always felt this real resistance to saying "I love you" and couldn't figure it out (this was long before I read about the split-attraction model or anything like it).
I went so far as to absolutely despise the word "love" when I was younger. I would cringe everytime someone said it, and there was no chance in hell I would say the word. I still try to avoid using the word as much as I can nowadays. Although I no longer despise it.
