He won't talk to me!!

So recently I went to my best friends house(guy) and we ended up making out and me giving him a hand job. We were going to do more, but his dad came home. But since then, I've tried texting him, but he won't talk to me! Did I do something wrong? Because HE kissed me first! Please help! I don't want to lose him in my life. He is my best friend but I'm not sure what to think now.
