"Fuck that" is perfectly valid. You don't owe them anything, and I think you should be extremely selfish in deciding whether to talk to them. You went no contact for a good reason.

What would you want from the relationship?
IF you decide that you want a relationship, having clearly defined reasons for why you're doing it will help in assessing if you're getting what you want from it, and if you should continue the relationship.
YOU call the shots. YOU define the boundaries. There are no wrong answers.
Want to talk to him (and him only) on the phone for 20 minutes, once a year? Perfectly fine.
Happy birthday texts only? Valid.
You like no contact? No problem.
