I am feeling exactly what you are right now. It's awful.. He has harrassed me every day for a week since he was served the papers. Yesterday was the first time I had a night with no calls or messages from him. It was lovely; until this morning. I felt sad and hurt. I just keep telling myself that I'm doing the right thing.
You know what the right thing for you is but it doesn't stop the flood of emotions. Stay strong - you can weather this storm just like you have all others in the past. Sunny skies are ahead!
