Do you have kids together?
If you don't, I don't understand why you would want to keep in contact with her.
Anyways here are my suggestions:
1. Call Display
2. Call Block
3. Auto email delete/block
4. Unlisted number
5. Tell her if she talks about anything else but your kids or you you'll be hanging up.
6. Tell her and/or family that you've met someone you really like, and they may not hear from you so much.
7. Change your name..lol...that last ones pretty extreme.
