Sometimes it can be awkward for other people who want to provide support but don't know what to say. It is personal + you shouldn't have to feel pressured to say anything. I usually say It's difficult for me to talk about right now. Other brief + to the point comments *I am trying to put the past behind me + move on. *I am trying to focus on myself right now. It's really no one's business what went on behind close doors. If your friends are respectful, they will understand. If not, then those aren't the friends you want to have
