<human>: Apparently I express myself in a way that makes it seems like I am in love with the people I date, when I really just want to make them feel valued.

I was seeing a guy [30M] very briefly, who didn't want to do long distance but had initially wanted a FWB arrangement with me. Some days ago he suddenly questioned that conviction, asking me "what if it changes things" between us. I said that it won't. He asked, how can you be sure, and I say "because you're not the love of my life? we'll never know that now. I don't know how I know, I just do."

A few days later, he tells me "don't think of me as the love of your life, I have many flaws..." And I was like "??? didn't I just say you weren't?". Then he says well you sounded like you was considering that possibility by saying "we'll never know now". What I mean was, since we decided not to be together then we'll never know if we have a future, so a FWB (because the sex is good and we also happen to be friends) situation wouldn't be too bad.

Did I make it sound like I was professing my love for him?

Now, Reddit. This seems to be a problem in my life. I say something affectionate (why waste time not telling people you like that you like them) and it gets grossly misinterpreted. This wouldn't be too much of a problem if I wasn't always so hurt by the end of it all. Because it always seems like the people I date value me less due to this perceived imbalance in our emotional investments. Am I just being too expressive? Should I rein in my affections a little so that they don't get trampled on?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I am not in love with the people I date, but it seems that way to them, and it seems to freak them out. How do I stop that without compromising the way I show affection?
