He won't leave me be

MY married lover left me for the final time when his wife announced she was pregnant with her fifth child.

- 

After four years together, and more broken promises than I care to remember he texted to say: “We're through”.

But we're not through because he's always following me and popping round.

I see more of him now than I did when we were together and, sometimes I weaken and have sex with him too.
