With the emphasis of "I Love You" from your pic, it is presented in a big way. OK, I'm an og=old guy. I have had some great relationships and some bad. The point being saying "I Love You" was a common thread with them all.
Finally, an avid reader of C.S. Lewis, I picked up his book "The Four Loves" and read it several times. It explains four types of love - Affection, Friendship, Eros, and Charity.
From his revealed definitions I realized I could say to a co-worker "I Love You" since we were friends and I was affectionate of her. Yet, the definition of Eros is not fulfilled. And, my degree of sacrifice regarding Charity may not meet a relationship standard.
At the same time I have male friends, therefore I can say "I Love You" too! but affection and Eros and Charity are not in the picture.
For me, today, as a single person, and my maturity meaning age - LOL, these may be high standards or then maybe not. I would say before I could emphasize as your picture does that I would like that person to meet all four criteria.
I think there is vast difference in "being in love" with the attached feelings and "in Love." Maybe it is affection and Eros yet really friendship isn't in the picture. Or any other mix.
I am not saying they have to be present at one given moment, yet I believe they have to be present in the sense of the soul, psych, and emotional attachment. Way too long of answer - should I post this - flip the coin - yup , , ,
