Ex-girlfriend and ex-friend now both mad at me for things I felt had to be done. Better off without them?

You did wrong by not telling your friend the right away the first time. She didn't tell him ether, and didn't tell you about getting with him. You're both better off without her, unless she agrees to be you two's tool, but I'm just joking and she will just cause more problems, so yeah don't do that ether. If he has what it takes to forgive you for hiding something from him, then you've got a really good friend that you should never betray again. You should buy him a hooker, that usually makes my friends feel better.
