So I split with my ex a few weeks ago after 15 years together and he is already with somebody new (a co worker) I am literally heartbroken and he just seems to have got on with his life. Ending it was the hardest thing I have ever done but he was literally never at home/various hobbies/nights, days out. He has already introduced her to the kids and they have booked a holiday! Meanwhile I am in a heap on the floor trying to process it all.
