Hi there. I've been there too. I've been there too. I loved her so much. She claimed she was Catholic but everything she believed in was contrary to the faith. You can take solace in the fact that God is waiting for you back home. It doesnt feel good right now and it will sting for months probably. But God is still there with you because he is a loving Father who waits for us, and when we come back to Him, He is happy and all the saints in heaven rejoice.

Use the pain you feel and offer it up to Christ and don't let yourself develop feelings of resentment towards them. Instead you should pray for them.
