I think whether you communicate them or not depends upon what makes
you comfortable.
I don't mean, "I'll tell him my boundaries, that will make him shape up!" but rather "I wouldn't feel confident enforcing this if I didn't tell him about it first."
I discovered that some boundaries I felt better after telling XABF, and others he didn't need to know so I didn't say.
Most of my boundaries were build
after he went to rehab, and I didn't get good at enforcing them until
after I decided the relationship would never work, so take this as you will. Just my two cents.
