I slept with my best friend

We were bestfriends for 5 years now. After being bestfriend for that long we decided to drink, only the two of us. we literally drank until were wasted. We are drinking at his yard and decides to come in for i am wasted and i can't even walk straight. We are very close that cuddling is just normal. So we cuddle and ended up having sex after 5 years. Now the problem is, no one wants to open it up. He don't want to talk about it base on his actions. I tried talking about it but he always have his reasons that he is going somewere and have a lot of things to do. So i just end up not talking about it two. I am afraid that we might lose the connection we heve. Up until now we don't talk about it. We hang out and acts casual. We even travel together. Its very hard to take your relationship the same way again. What do i have to do. Its been months but still we don't talk about it and i am afraid to askm so i am asking for an advuce, coz j really dont know what to do.

I like what SusieDog says...also, maybe you realize now you have to stay "friends" because this is making you feel "weird". So...I would bring it up and say....Hey, that "night" or that "thing" we did is in the back of our heads and behind us right? It was weird...but I don't want to change our friendship...can we just pretend we were "black out" drunk and forget it? I do think you have to bring it out in the open because you BOTH already know about....and both afraid to address it because you both probably feel the same way "weird" and realized what that kind of relationship would do to your great friendship...You can do it! It will feel good to get it behind you.
