What in the world?

My husband has been more agitated lately and legit told me tonight that when he saves up money to file for divorce he will. He keeps saying that it’s me, but he’s always rude with me and if he’s nice for two days max he says “but I’ve been good to you” he told me before he’s not attracted to me anymore, misses his ex wife, and most recently that he likes texting while at work but he hates looking at me when I walk through the door at home. I don’t do anything. If I am rude I told him it’s because I’m defending myself and don’t want to let anyone walk all over me. 🥺
