It's easy to fall into the pain-- it almost feels good (it feeds my martyr complex). Hallmark, movies, songs, and TV have taught us this well. The fact of the matter, as you have shared, is that it was time for it to end, and the house is not lifeless, it's drama-less which probably feels the same to you right now.
Learn to love the lack of drama, and yourself. You will be fine.
