Like the Admin and Azure&Vanilla said. What you're doing is wrong and the fact you ask "how to cheat" when you have clearly already done so. Through texts, video chat, or whatever medium this may fall under. This is wrong in general, in any kind of relationship or marriage. You have the willpower to...

Having a stuffie
Drinking Chocolate Milk or apple juice (although that kind of sounds weird)
When I am told I am good by daddy.
Disney Movies/Pixar Movies
Coloring
Playing Video games (It's like I am in a whole other world!)

I too have asperger's. It makes me quirky but that's okay I have learned to enjoy being different.
