Encourage me, please. My husband refused, and now I have to follow through

This is the letter I wrote to my husband, after he went out to a bar multiple times, blocked me every time he did, didn’t wear his wedding ring because he “lost it”, did coke one of those nights, and admitted to flirting with multiple women and texting some of them. Also, I called one of the numbers in his call log, and the woman admitted to knowing him and then flirting and talking about hooking up. She ended up denying him because she didn’t feel right about it, but he kept asking her multiple times. She said she didn’t know he was married with kids. She also told me all of the details he told her about his life. Details like the truck he has, the job he works, where he lives, etc. Everything he told her was a lie. I have tried for the past month to work through this, and I am in such a deep state of depression right now because of it.

After reading all of this, my husband said, “I’m not taking a fucking lie detector test. Why don’t you google ‘wife tries to make husband take lie detector’ and see what kind of response you get from other women. They’ll call you crazy, like you are.”

Maybe I am crazy, I don’t know. I just know that I’ve tried literally everything I can think of, and my husband doesn’t care anymore. He isn’t trying to work on this marriage at all. The reason I’m waiting to leave until June is for my daughters sake. She is in tuition based school currently, and the town we will be moving to doesn’t have the classes she needs. So I don’t want to stunt her academics because of the relationship between her dad and I.

Also, the reason I want a lie detector test is because he says the woman I talked to is lying, and that he doesn’t know her at all. I even showed him a picture of her, and he denied ever having met her, let alone trying to sleep with her. He told me that he thinks she is making up lies just to mess with me because some people are just mean like that. I’m totally confused and just want a definite, 100% truthful answer. I feel like a lie detector test would do that for me. But the fact that he is unwilling to take one makes me think that I am right in my suspicions, and that he did cheat on me and that he does know the woman.

Please give me some encouragement.

Do you think I’m crazy for asking him to take a lie detector test?

Thank you.
