(25F) unsure about feelings for close friend (24M)

r/

So, I (25F) have a guy friend (24M) and we are quite close. We go to university together and we’re always hanging out. Our talks have good banter and sometimes, flirtatious undertones. We tell each other alot of things and keep each other updated. However, last night, we had a chat about talking stages with other people. I asked him about his but he didn’t tell me. We respect the others’ decisions but this one bugged me. He told me that it was online and he’s still friends with her. Our friendship is special but at that point, I wondered if he had feelings for that girl. I’ve been under a faint impression that he did have feelings for me based on what I’ve asked him about an ideal woman for him but he never mentioned this before. I told him mine but he wasn’t able to tell his, for some reason.

After last night, there’s been a strange feeling in my chest and I’ve been upset. I don’t know at what or who but it’s been hard thinking that maybe he doesn’t have feelings for me. Something feels changed and when we talked about it, he said he wants no distance and doesn’t feel any different. What should I do and what can I possibly be feeling upset about?

TL;DR: Had a conversation about people we’ve had talking stages with. I revealed, he didn’t. Now, I’m thinking whether he likes me or not, causing me to feel upset.
