Dear Annie:

You can take a break from thinking about him by taking a fast walk for an hour, outside in the hopefully fresh air. The fast walking, the physical exertion will clear your brain from thinking, for a while.

When you think about him again too much, you can take another break, maybe do some physical work, even washing dishes, but do it while paying attention to what you are doing. That will give you another break from thinking.
