I meant continuing to look for yourself at where you are with it (as you already seem to be doing) and choosing to stop (or not stop) being hard on him at your own pace and as it suits you -- not in response to group pressure nor to accommodate someone else's trigger points.

I know there are some forms of group support that involve everyone else deciding what's "good for you" and then leaning on you to go along with it. That's never worked well with me and I'm guessing you're not too keen on it either. My biggest question always seems to be whether the group really is looking at what's best for me or only at what's most comfortable for them.
Oh, what you just said, for instance:
If it's everyone reacting individually there may not be much you can do about it except try talking to them about it one on one or just getting away from them. If there's anyone in a position to speak for the group or to take charge of what's going on, that would be the person to approach first. I can not see any justice or sense in sacrificing your feelings to spare Richard's, especially since Richard still seems to think that he was entitled to pressure you for sex and that it was bad form for you to deny him.

I can also see where Connor might need careful handling, if you think he's at all inclined to fly off the handle and go after Richard.

TPND, you're obviously in an uncomfortable situation here and seem to think you're not handling it well. You may hate me for saying this, but for whatever it's worth -- I find it hard to imagine you handling it even half this well three or four months ago. I say you're obviously growing (though amid more than your share of growing pains.)
