You are hurting...I know. She loves you and gets you to a good place in the end of the conversations....I always did, too...didn't want to see my H hurt like that.....
It may not be in her right now. But, like you said, you are still married. I'm glad you are going to see the movie (I know it seems wierd me saying this over and over) and it will help you know what to do. You WILL keep up the fight because you love her and you know what God wants. It is NOT you, it is her. SHE will have to make the choice to stop the mess. Your choice is whether to still love her or not....easy choice...she is your wife. You know...it might be good for your ss14 to come see the movie with you. Possibly d11. They would understand what you have been doing and you will teach them what is right. Get a babysitter for the little ones. THis is a good idea. SHould have thought of this before.
