Champion.... only you really know the right answer to that. Listen to your heart and be honest with yourself about why you want to maintain a friendship. If your reasons are honourable then she may be open to hearing from you again and growing your friendship.

I don't think its ever a good idea to stuff feelings. You need to confront them and be honest with yourself about them. It doesn't mean you will have any kind of relationship with your ex again but you do need to find the closure you need to let it all go.

If you can have a healthy and honest friendship than that would be great but if you can't then leaving her be might be the kindest thing you can do for yourself and for her.

Keep your intentions honourable and you will find the answers you seek. Give it all some time to ensure you are not reacting to the loose of a habit, a routine in your life or some need unrelated to your friendship but caused by a new lonliness. Let the lonliness pass before reaching out to reframe a friendship. That would be my advice but I'm not expert. Just someone who cares about you Champion.

Wishing you wellness and clarity in the days and weeks to come. Make the extra effort to spend time with family or friends with whom you have a special bond. Feed your need for comforting and unconditional, uncomplicated loving relationships. They will nurture you through these troubling times.

Take care........
