You got those butterflies! Like, for instance, I spent weeks recently convinced my friends secretly thought I was a slut because of the aforementioned same exact situation, and I'm pretty sure they had absolutely no idea I was even worried about that. If so, I would be Very Happy for you both! Yes, in a way, you may be helping one friend by confirming that he is definitely over his ex or that he is really, truly, into her. Friends dating friends can be awesome. People generally don't undertake a long con in the hopes of convincing someone they don't actually like that they like them for some weird reason.
It can be jarring and suck, at first.
Are my friends secretly dating each other?
Encourage any friends to speak to each other directly about issues they may have with one another, and every will be happier for it in the long run. I was in this exact same situation once. If these two friends of yours are dating, and choosing to keep it from you, it most likely is occurring for reasons that have nothing to do with you at all. I might be thinking too much into it, but I just don't want to be strung along for the ride. Whether you are playing a middle man in a relationship, a work environment, or in between friends, you could be doing more harm than good.
