<human>: Can you succinctly summarize the text in 1-3 sentences?

A few weeks ago, I met up with a man who I met on Tinder. I made it clear to him that I was only looking for sex, and he agreed. We've been together a few times, and enjoy a lot of sexting and sending pictures in between our meetups.

A few days ago, I noticed his texts felt a lot more romantic. He sends me messages like "Good morning, beautiful!", and tells me I'm an amazing girl. His last text to me says "You're the perfect girl."

This doesn't seem like the behavior of someone who is only interested in sex, but I'm not sure what to make of it. I don't want to ask him if he has romantic intentions for our relationship, in case it scares him away. 

What should I make of this situation? How do I respond to these texts?
<bot>: A man I'm in a fwb relationship with is sending me romantic text messages, and I'm not sure how to deal with it.
