This episode pertains to my experience when you have the absence of compassion and that closeness and loving words can lead to the thoughts

Of infidelity from the person with BPD because they figure if you're not acting loving towards them and offering loving words that you must be offering all that to somebody else so that can be a huge trigger and either end up with them splitting or slowly leading into a much bigger and explosive argument either lasting the normal time that your person splits or any longer period of time.

So this is views and suggestions for my personal experiences in regards to the subject.
