It's the voice of experience talking. I've experienced that uncomfortableness. True friends of yours will be delighted, but guarded. They don't want you hurt again. At some point a friend will ask what is going on. I think this is the type of situation where everyone is uncomfortable at first. And it really does come down to "what if I say the wrong thing?" " I want them to be happy, I don't want to be responsible for causing a disagreement."
When you can't make a decision because you are torn between your heart and your head, listen to the half with the brain.
