I like my best friends brother. awkwardddd :/ help?

I made out with my friends brother and went out with him for a while, but she was okay with it. I really dont think it's that big of a deal if your friend doesn't care. Age doesnt matter in a relationship unless if they are old enough to be your parents which he obviously isn't. But maybe he hasnt been talking to you because maybe he thinks that you like him. Some people are like that cuz its weird for them. dont bother him that much thats not gonna do u any good.
