I have had a talk with my parents on this subject, as I am planning to visit and ordain in Amaravati if everything goes well.
My mother told me that she wanted me to phone her every week or every 2 weeks or so.
I told her that that is not possible to have contact on a regular basis like that, but I am not sure about it.
Personally I think that she is still too attached and looks for ways not to "lose" me.
I can feel her pain and clinging, but I have no interest to give up my plans to ordain.
Since the beginning of this year I am watching the mind closely and have had some great breakthroughs.
The heart wants to join the Sangha and nothing else.
It's like seeing an escape from jail and prisoners(my parents in this case) trying to hold me in prison.
Her clinging is actually pushing me further and makes me want to visit them less.
She still wants to control the situation by keeping in touch after ordination, I guess out of fear or attachment.
If it's up to me however no contact at all, except in case there are major issues like sickness or death, would be the best.
So what are the rules actually?
"Then you understand the brilliance of the Buddha's teaching of anatta, goes right to the heart of everything.

From the body into the mind thinking, from the mind into the doer, from the doer into the knower. You can see you're not the knower, you can see you're not the doer..."
