Yes, you just keep talking about it until it loses intensity and gets resolved.

I hate those type of sessions, but in the long run, they help me see how to work out conflicts and sort through what's trustworthy about a person. Of course, if the therapist gets snitty and defensive, that's a whole other thing. But that doesn't sound like your therapist at all. Just let it keep airing out. Don't shove it under the carpet.
