You handled the family picture situation very well. Maybe it was his way of hurting you in a passive-aggressive manner. But, you did the right thing by telling him he was correct. That cut off his baiting you into a heated discussion.

You've had a lot of things happen in your life the last few years and now you need some time and space to heal. It's good that you've gotten to the point of not caring that much and that's called detachment and/or dropping the rope. People in crisis can sense when we've detached and will try to bait us back into their drama and this could what the family picture incident may have been about...but whatever is going on w/him is all about him.

Continue on your path, take the time to find YOU again. It's okay to leave the door ajar and see where things go.

Don't be a stranger...when you need to chat, come here. Someone is always around to listen and offer advice.

Take care.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
