LookingforCalm, I essentially agree with Perna in that your ex is only gratifying himself by contacting you with these personal tidbits and other news items about his life. He is seeking a version of the emotional intimacy he once had with you, and you should not reciprocate--let his wife be the one saddled with those duties. Knowing the struggles through which you've been in your relationship with him, he comes across as a total cad by announcing this news to you, with the additional caveat you keep quiet as he hasn't told anyone else yet. Ugh. No offense, but he sounds like a slimeball.

Ignore him--simply drop out of his life. Don't tell him why, and don't respond to his texts. If you encounter him at a store or restaurant, say your quick, courteous hellos and get the heck away from him. Don't allow the remnants of your past with him to interfere with the life and happiness you are building today. He isn't worth it.

All the best to you.
