Don’t be silent. Grovel. Woo her.

But be prepared for her to still have doubts. You well know that having and raising a child is a huge lifetime commitment, and she’s right to question your commitment to that since you’re only doing it to get her back (and before you protest, if she disappeared tomorrow, would you be looking for a new partner to have kids with? No).

Because your actions didn’t match your words, you DID waste 6 years of her prime child-bearing years. What could you do now in ACTIONS, not words, to make it clear to her you’re sincere? Move to where she is? Propose marriage?
