best friends bestfriend?

To make a long story short, I recently met one of my best friends, best friend.

Since then, my best friends(we will call him Nate) best friend(We will call him Caden) and I have been hanging out A LOT. My best friend Nate, recently got a girl friend, and for the past year, i’ve also been sleeping with Nate. Since he got a girlfriend, we obviously haven’t, therefore we have been a little distant. I still talk to Nate everyday, however Caden and I have been hanging out pretty much everyday without telling Nate to avoid drama. Caden and I have gotten super close, like facetime everyday all day close. Nate got upset when he found out we were not telling him that Caden and I have been hanging out.

Long story short, Caden and I are starting to flirt and I really like Caden, however no touching or anything more than JUST occasionally flirting, and I am not sure if Caden and I will ever even be more than friends.

Is it wrong of me to talk to Caden? I really like Caden and think he’s super super good for me. However I’ve been friends with Nate for over a year now. Some people I talk to, say that I need to do what is best for me, and other people say that I should not ruin my friendship with Nate since I’ve been friends with him for way way longer than Caden(I’ve only been friends with Caden for like 3 weeks now)

Caden is also never really busy, he is pretty much always available unless him and I working, and he’s super fun, while Nate is ALWAYS busy, to the point where I see him once a week.

Is it worth it so continue to hangout with Caden even if it could possible ruin mine and Nates friendship in the meantime?

I need advice from people who are not involved so please help😭
