My heart goes out to you. Do whatever makes YOU the most comfortable. If you think you'd rather talk on the phone, then you have that right. If you'd rather just email him and ask him what it's about, then do that. And if you want more time before you have this talk, take all the time you need. Treat yourself with dignity and he will respect that.
You are a strong woman and you WILL get through this even stronger no matter what the outcome.
