You'd be better off to solve that problem looking up what minecraft is instead of asking here how you can show him that you understand. Just make him ask you "What is Minecraft". Then of course you explain to him by showing him you know what it is. And of course you can always play a game of it with him.
You can be in the Minecraft crew by talking to Notch (Markus Persson) and if you prove your skills, you will be in it.
prove to him that you really love him and want him back and if he still cares for you than he'll understand you and go back to you
Prove to him that you aren't.
Tell Him
prove your loyallty show him that you can be trusted.
He will forget about you and he will keep it a secret.
You could succumb, and learn to love the game.
just tell him and follow your heart
prove it to him by kissing him
There is no way to prove love. You have to believe in the person and trust them. And also go with your basic instincts.
Trying to prove something like that will convince her that you dont need him she should notice it by herself.
i sugest you knok him out and prove to her you have a big D I C K
