"Hope you had a good Easter. I’m done being in limbo, need to move on."
"I’m done being a string along. I know it’s only been 12 days but I’m his wife, not some girl he picked up at a bar"
"He’s a coward and is bailing, and I’m sick of being the string along."
"I’ve been dark since Sunday night. No contact, nothing."
I see this as someone who is deeply hurt and REACTING to your anger and betrayal by closing yourself off emotionally. And that's okay if that's what you have to do to get through it. It's a coping mechanism. And you'll survive and even thrive in the end.
But if you want to challenge yourself to dig deep and learn the most and MAYBE have a chance at your M again, you'll have to acknowledge the deep hurt and face it & grieve. I did a grief group last winter that was geared towards divorce & death of spouse. Really helped understand my feelings. Maybe you could find a support like that.
You're doing a good job keeping your head above water shiss. These feelings will have to be sorted out, though. Either now or in your next relationship. Lead with hurt, not anger. You are entitled to your hurt hon.
