I have no idea where you got the idea of anyone being sent to hell from that scripture since it never says, or even suggests such a thing. It states that a married couple should come together to help prevent potential problems in the marriage, such as infidelity. Nowhere does it mention anyone going to hell. So it seems this is something you have fabricated in your own mind.
As far as offering anything more specific about your situation neither I, nor anyone else here, can give any real information or advice as there is no real information given to know anything to say.
I would, though, advise you to seek counseling. Both you and your husband could benefit from healing and recovery. If trauma is a problem from your past there is a highly successful method for trauma called EMDR. It is essentially mimicking REM while focusing on the trauma. I looked into it, in the past, to ensure there was nothing questionable about it mentally or spiritually and found zero concerns. I tried it a few times, but it didn't fit my personal situation. But i did get the experience to know it is a safe method.
Counselors should be trained and licensed to use it. Here is a link for you to look more into it, if you are interested.

I hope you can find some healing from your past trauma, one way or another.
