That's gonna be a little bit difficult because she and I share many friends. If I would cut ties with all of them, I'd lose half of my social circle.
But I guess I should either go deep or go home. I could always make new friends...
So you really suggest I should cut all ties with all our mutual friends?
I thought the same thing about 5 months ago, and I met her family, her friends and whatnot.
Bottom line, they knew HER before YOU and even if YOU were the victim and you did everything right, they will ultimately take HER side, even if she is wrong.
In my situation, I had a smart old friend (he is elderly) that me and the ex knew, but COMPLETELY took my side and he's known the ex for 20 years and me only 3 years. Even he told me to stay away from all of them and the ex, and that when he saw us together "I was excellent for her, but she wasn't good for me" and that he thought of me "as a son he never had." Luckily this man knew all what was up and told me the right things, and not what I wanted to hear.
Now if you knew them before your ex did, then you can keep them BUT WATCH WHAT YOU SAY AROUND THEM. They might prove to tell her about you and what you're doing, knowing this about you, she can have her cake and eat it to.
Trust me. You REALLY want to heal? All balls or none, stay friends with them, you will just prolong your healing. I went through it. Things got better when you let everything go, AND if they are your true friends, they would understand. If not, they weren't your friends were they?
If there is a "that's not a mature thing to do" arguement, then lets say this:
Was it mature that your ex dumped you, and selfishly thought of his/her own needs, while you worried about his/hers?
Was it mature that you (More than likely) were labeled as the person who made the relationship not work, even if you know that is not true and you gave your all?
Was it mature that your ex LIED/CHEATED on you?
HE/SHE DESERVES NOTHING FROM YOU
HE/SHE DECIDED TO LEAVE TO SEEK GREENER GRASS
YOU SHOULD BE PISSED!
Move on, then when he/she comes back, AND HE/SHE WILL, you can handle it like an adult.
From what I've seen a majority of the time, when you finally move on, they decide to come back, the reason they come back is what you have to look out for, but more than likely you should say no, because they will do it again.
