is is it normal for the WS to struggle to let go of communications with the Op
Normal? Yes. Acceptable? NO.
I'm sorry that your WW suffers from mental illness, I truly am. I agree with the poster who suggested bringing her parents into this to help when you lay down the line. This does not necessarily mean D, but if you don't provide boundaries (no more OP), she won't stop.
I don't know the backstory, but saw that a poster mentioned that the OP was (is?) her therapist. If this is the case, he must be reported (even if he is no longer her therapist) - that is a HUGE violation of the code of ethics in the medical profession and I guarantee you that he's done this to his female patients in the past, and he will continue to do so to his female patients.
I don't condone taking your child away from her, but if you do decide to separate, supervised visitation may be necessary until your WW gets the professional help and/or meds that she needs to get well. If your WW is willing to get intensive IC, and go NC with OP, your M may have a chance, but it has none while she's behaving as she is now.
Or, you can stay with her and let her have contact with OP...that's up to you - we're just strangers on the internet. But I promise if you take this route, your soul will be destroyed and you may end up with mental health issues yourself. I'm sure that you don't want that for your baby as the baby needs you more than ever right now.
Sending strength...
