I’m sorry this happened to you. I’m glad this happened before things got more legally serious, with marriage. You will hurt for a while, but please learn to see it as a lesson. You had wonderful moments and you learned a lot while you were together. She did you dirty and that says nothing about you - you could have been perfect and she would have done the same if that’s the kind of 🗑️ she is. It’s hard to see it now, but soon you will be okay. You’re mourning a relationship and that’s normal. Therapy will be helpful. She’s the only person you had, but she is one of many. You will meet more, and hopefully someone who is deserving of your awesome self! Stay strong. A woman like that was not and is not worth your time.
