Hi streda05
Welcome to bpdfamily. The situation you describe sounds quite difficult indeed. You've returned for your children's sake, how long did you leave?
We have certain tools here that can help you find new ways of communicating with the BPD person in your life. I'm specifically thinking of our article about the things we can do ourselves to end the cycle of conflict and our article about validation:
Ending the Cycle of ConflictCommunication Skills - ValidationThere are also other tools that can help structure your communications with the person with BPD such as
S.E.T. and
D.E.A.R.M.A.N.. Are you familiar with these tools? They can help you express and assert yourself in a way that minimizes the likelihood of (further) conflict while maximizing the likelihood of getting through to the person with BPD in your life. These tools can also help you stay (more) calm yourself as they help you structure your communications and anticipate what might come next.
How long have you known about BPD? Has the person in your life been officially diagnosed with BPD?
