I took a step back 2 years ago from a group where my ex was also. Have been getting on with things with a new group and gradually settling in. I keep in touch with those I was closest to outside of old group, but now that 2 years has passed, they're encouraging me to return, but I still don't want to have anything to do with him after how he treated me at the end, even though the others are nice people.
Am I being silly?
