What is a really clear sign i'm over my ex?

[Joe]

When you ask this to people, they say "listen to your heart" or "listen to your mind" bullsh*t i want a clear sign to know if i'm over my ex.

Whenever i think of her, i just feel bored like if you played a videogame over and over you just feel like buying another video game or doing something else. When i see her pictures i don't find her as attractive as i used to and i just miss her when i'm really horny. She has tried to hit me with that "remember when we...etc, etc" bullsh*t and i try not to follow the convo that much. I have her blocked on my facebook and i haven't texted her for a month or so and i want to keep it that way. I might be confusing the fact that i miss having a girlfriend with the fact that i miss my ex but do i sound like i'm over my ex?
