It is hard to let go of the marriage, especially when children are involved. I had a heck of a time with my ex-hub! We did remain on "good terms", which was important to both of us (to make it easier for our girls), but I certainly shed more than a few tears. You were together for many years. Some times weren't the greatest, no. But, there were also some good years in there too ~ and I think that it's healthy to remember those times. Rather than putting the whole marriage in the "negative" department. You have a beautiful son together, and he will always be a reminder of those happier times. My girls bring up a bittersweet emotion in me. Not every time we're together thankfully, just occasionally.

Gentle hugs to you ~ take care!
