Sorry, I feel i must clarify ... do you mean another part of you, or do you mean a real life partner?
If it is another part of you, then perhaps that parts needs/ wants to have voice, not necessarily here - any piece of paper will do, tape recorder, talking to T, drawing, etc. Do you know why this part wants to silence you - i mean that's a common theme of protection that usually isn't necessary anymore, but it is something to be worked through and negotiated. If that part doesn't feel safe, it isn't likely you will find peace when you try to speak. In the end, only you can figure this out using your own inner wisdom.
I'm sorry you are in the midst of a struggle; it's hard. Give and take, patience and just time will all contribute to healing. Wish you safe journey.
