Most Helpful Girl
Well I am friends with my ex. We had been together for a good few years and have remained friends since the break up. Was in contact with himeven when he was dating. He did tell his new girlfriend about the fact that he was in contact with me. She apparently didn't mind.
You see the thing is that I do believe you can be friends with your ex, but only if you have been together for a long time and were friends before or have a deep connection to each other even outside the relationship. But I don't believe in being friends with all ex's, especially ones that cheat. It would make no sense. But the fact she never told you tells me that she hides things and maybe was afraid to tell you in case of your reaction.
Chatting to ex's is OK once there is nothing going on or feelings lurking in the background. I think openness and honesty as the key. Clearly you did the right thing in moving on.0THIS IS NOT RELEVANT ANYMORE
