I’m on mobile btw

My maid of honor is my best friend and has been single. My SOs best man has a girlfriend but has been flirting with my friend or kept asking me if he had a chance. I got fed up and when my friend was staying over I had them chat. 

My SO agrees on them trying out since he knows everything about the girlfriend. (She’s a gold digger who took money and hates it when he hangs out with my SO)

She stayed over for 3 days the first day was girls night and the next day we were invited to go see captain marvel with da boys. Later in the night was bonfire and we chatted playing truth or no comment. Or asking weird questions like if you were a dragon what dragon. It was a laughing fest they exchanged numbers next day best man invited us to go eat and hang out at his house. They bonded more and I notice the best man was like a guy who found out his crush liked them back.  They hit it off. I didn’t ask what happened but my friend came back blushing. I did ask her if I was pressuring her into dating him. 

She said no because everything felt natural and if anything she had a new friend to hang out with.  

I’m wondering if me and SO are assholes because when I asked his best man if he liked her he said he doesn’t think it was right but kept going along with it because he wanted to be happy.

Additional INFO: Maid of honor knows about his girlfriend. She sees it as two ways either it could be or just have a new friend. I only once left them by themselves because I needed medicine for a fever. The whole time best man been flirty.
