My friends called me a traitor when I’m starting to go out with another guy when I knew our guy friends liked me for year. Am I wrong for this?

We’ll I started my new job about two months ago and it’s going okay. I met this guy during lunch break and we just started talking. Then for the next couple weeks we’ve been chatting. He asked me out in a date and I thought about it and then said yes why not. So that Friday night we went out for dinner and it was great. A week later we had our second date. I didn’t tell my friends yet because I wanted to see how things go. He said he would like to go on more dates with me. We’re planning a third date. I finally decided to tell my besties about it.

My best friends (let’s call them Anna and Alexa) was like shocked. Anna said, “Wow that’s very cool. You didn’t tell us you were seeing someone.”
I told her we’ll I wanted to wait until the right time and they both asked what he what he was like and what he does.
Alexa asked, “Is he special needs like we are?” I said I don’t even know.
We’re all autistic but high functioning. My besties have boyfriends but they’re also special needs.
Anyways one of them asked, “Wait a minute how does (our guy friend) feel about this. Did you tell HIM about you’re seeing another guy?”

I froze. Then I said, “Um…. I’ll tell him soon but I’m sure he doesn’t feel anyway about this and we’re just friends. Why would he know?”

They both looked at me and said, “Are you kidding us! Come on! He OBVIOUSLY likes you. And he even said you were his “girlfriend” when your dad asked if he had a girlfriend. I told him he was joking around. We’re just friends.
Anna said, “Well did you tell him that you don’t feel the same way because he’s going to be REALLY hurt.” He knows we’re just friends and I told him straight. Alexa said, “Traitor! This boy likes you for YEARS and you took him for granted and NOW you’re seeing another man? You stringed him along. He’s going to be really hurt you know. You need to tell him and let the guy you’re dating know.”

Why would I tell my date? Am I wrong for dating?

Plus if my guy friend still likes me for years, he would have made a move and asked me out on real dates by now or call or text a lot? I know we went to dances together twice but as friends. Even my parents know he likes me.
