As a sensitive/empathetic person, trauma dumping is a big trigger for me and I have cut people off because of it.

The most important thing for me is that they are seeing a therapist to help work through the processing of the events bc I am not someone who is qualified to do that kind of emotional work, a partner is not a therapist. The intention is also very important. If you’re going to bring it up, I want to know ahead what we’re getting into— why are you bringing it up, where is the conversation going, what are you expecting from me in this conversation/how are you approaching this topic? If we’ve been together a while it could be as simple as “these things have been on my mind and I am working through them with my therapist but would like you to know why I have been feeling off lately”. If you’re not sure whether or how much to bring up, I think it is best to ask whether or not the other person is comfortable hearing about it at the moment.
