Wife left, when does the heartache get better? Christians Please!?

My wife and I have been married for 9 years. We have a wonderful 6 y/o son. 5 years ago, my wife told me that she wasn't in love with me anymore. However, she stayed in it for the sake of my son. I had 5 years to try to find out what was wrong and repair it. I did everything I could possibly think of.. But, about 3 weeks ago, she told me it was time for her to leave. She moved out last weekend. We have split on good terms and have agreed on everything. She knows how very much I love my son and how important he is to me, so she agreed to joint custody, equal visitation, etc... And, she only moved about 5 miles away. The problem is, I am so much in love with my wife. I just don't know how let go and move on. I have given all this to God and I know he is in control of the situation but sometimes you just need the encouragement of others who have been in your shoes. Thanks for taking the time to read this and have a blessed evening.
