You can't turn the "love" off because you two shared a life together. It takes time to detach and move forward.
About your friends, they mean well, but you need to tell them that you don't want to hear about what he's saying and doing. This "gossip" is bringing you down and they don't realize how this is affecting you. Trust me, if the shoe was on their foot, they wouldn't want to hear about his behavior either.
In MLC, it's all about them and they don't care what people think just as long as they are happy. It's about self-gratification and numbing the inner pain and they will do what they need to do in order to numb that pain.
I know you love him and his behavior is hurting you deeply, but you've got to keep the focus on you for now.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
