"Didn't know you were comming."

After everything you've done for him, taking care of his needs(emotionally and physically), just when you weren't able to fulfill his desires, he decided to cheat on you... well... not cheat, you two weren't even officially together, or were you? Atleast you thought he kinda liked you enough to wait a weak till your period is gone, but right when it was gone, he couldn't wait any longer.

English is not my first language, so there might be grammatical problems.
