No, heartshaped. She's not ok. I don't know whether your friends will support you; I suppose if they are true friends they will. The difficulty is that YOU have changed. The ethos of the person you were has evolved into something that you've made acceptable to yourself. I think that causes damage to a person, to you.
Ask yourself if you're avoiding your friends because you think they won't accept you? If you can't answer that question ask them because you have nothing to lose. If you won't end it with this man you're setting him up higher than your friends - higher and of greater importance than even yourself. You may love him to the moon and back but... how much does he love you? Don't answer that on the board - answer yourself because you'll get a true reflection of the answer that way.
I asked the same thing to Sarah (my friend) and she thought about it - and got angry (with me)... and I knew what the answer was because she did.
You're in a 'bubble', just like Sarah was. It distorts reality to such an extent that you can't recognise things for what they are because your affair is all encompassing, it's the only thing that matters to you right now if you're honest. That's why all the posters telling you to think of his wife and his children are wasting their time. People will always focus on the thing that is most important to them and they are inherently selfish - all of them.
Sorry to ramble... to answer your question. Sarah is still my friend; it's nominal really because as much as I'd love to get back to where we were beforehand, she's not the same person anymore; I am. I still love her, she's my friend but she's like a shadow. She still only wants to talk about HIM and it's two years after break up. That's how I know that 'shunning' by the general public makes absolutely no difference to her. She's joined an OW forum... I sent her the link to say, "Look Sarah, these women are in the grip of a horrible obsession, you don't want to be there, look how desperately unhappy they are?". She's joined them. Oh and him? He and I work together sometimes. I can't change that. I can't bear to look at him, happy and smiling and content. I don't know if he has a replacement, I suspect not because Sarah went to his home, had a bust-up outside in front of his wife and laid down in front of his car. It was my worst nightmare at the time.
Affairs are a CULT. You have a window of escape and if you go through it, it will be painful, but though that window is freedom and eventual peace and recovery.
With every ounce of persuasion I have, heartbroken, I'm urging you to find those window locks and GET OUT NOW. Not for him or his wife, his children, random people on a chatboard, but for you. Walk away and never look back.
