I don't think I can get over my husband's past abuse towards me.
Why can't you get past how they treated you?
He said a lot of really demeaning things and I don't think I can forgive him.
That's unfortunate that your husband was so unkind to you. I can only imagine how that made you feel, but your relationship won't work if can't get over past indiscretions. As long as your not still being abused, perhaps you can learn to trust your husband again, I'm sure it would make you happier.
Is it wrong to not want to trust someone who caused you so much damage?
I don't blame you at all. If you don't think you can trust him it might be time for a divorce. Some things are just irreconcilable.
