@Tatiepot that's wonderful to hear and both you and I and our sons sound like fairly similar characters, so it gives me lots of hope. Can I ask how old your son was when you split and how it affected him at the time? My biggest concern is the damage our split may do to our son, who has a very loving relationship with his dad in spite of everything.
And, to get back to the theme of the thread, I am really looking forward to only buying and preparing food for my son and I. Taking a very low-key picnic with us today was so fun and easy, but never would have been considered 'lunch' by my STBX, so we would have had to buy something out or rush home to start preparing a proper lunch in addition to the picnic. And in the back of my mind I'd be planning it while we were out, so that I wouldn't get caught out without a plan, which just kills the joy...
