I've been having a similar problem.
The Wild One gave me some great advice the other night. He told me
that once I've started an interaction and I get to that point where I
want to eject (and i feel it is too soon)... to push the interaction an
extra 10% further before ending it.
Just say SOMETHING, even if it doesn't quite make sense at the time.
You can also just pause for a second or two, gather your thoughts and
then say something. Of course, having something planned to say also
helps.
The idea is to just push the limits a little further each time you reach a
roadblock or sticking point with your game.
