Her anger and resentment seems so unfounded and I am so confused. I don’t know where to turn, but I am deeply heartbroken and just want the happy, kind, honest woman I initially fell in love with. This person she’s become is not one I recognize. I feel tricked and decieved.
You have been tricked and deceived. I don't know how much stuff you have at her place, and what financial burden it would put on you to replace it. It may be worth it for your peace of mind to simply write it off and fix in your mind you'll never get it back.
You could see it one of your friends would be able to take the trip with you.
I'm so sorry for what's happened. I would suspect that she may have been drinking and hiding it. That's what alcoholics do.
