Not getting honesty, doesn't matter if it's positive or negative, can create paranoia and eat you from inside. You're thinking, for example, does these persons create a certain atmosphere when you join in? The only thing you can do is put them against the wall and demand honesty, but it's risky since it might change something to the worse. Or you can try to "decide" what they're thinking about you, but then there's the chance that you create a bubble which will burst when they actually say what they think or you hear something which you weren't supposed to hear.
Perhaps one needs to be in the background, for a while, if there's the suspicion that a group are growing tired of one's presence or certain behaviour. You're not being frozen out, you're still part of the group. Maybe it can give some opportunity to view matters from the sideline and rebuild a cracken wall. Just don't let them slowly push you off the cliff.
I don't know what your place in the group is. But sometimes the deck of cards can clash with the permanent Joker or King. And one could use the time just to blend in.
I'm not sure if these rantings helped aything.
