I love love love your "little big update" T, thanks so much for posting. I've always been a big fan of yours, and your broken heart broke mine too. I wanted to shake some sense into NG, slap him around a little and make him see what is required of both parties to have a good relationship (it cannot be just one doing all the work and all the giving) and make him see what he will be missing by losing you.
But I am amazed, awed actually, by your growth and maturity because of this crap. Both for realizing that the fact that you and NG cannot give each other what you both need at this time does not mean that your love was not real. I think your IC is awesome too, and that writing him an email for closure is a great idea. And also for deciding to meet some of your own needs by joining the gym at D8's YMCA. That will be great for both of you, and I am so proud of you for making this decision.
And PS, ugh to your ex F*ing up your taxes, the big idiot, and going to Israel sounds wonderful -- you can get a certified copy of your divorce decree at the Superior Court of New Jersey Records Center -- 609-421-6100.
