Music,
I'm relatively new to this site and I just wanted to say I feel your pain. It's been about 2 months since I last saw my ex. After a year and a half, he could have cared less that I walked away. Of course he acted like "good riddance" just days after speaking of his love for me, our future, his plans for us. Blah, blah.
I'm not anxious all the time. My nerves have calmed. I'm functioning better at work and with family. I am, still, sad at times. It's hard. Hang in there...
