Your OP is chilling, and some things stand out to me.
You say that he says he loves you, but it sounds like you have realised that words are cheap and he doesn't show you that he does. I agree, it doesn't sound like his actions are driven by love.
On the subject of love, you say you really love him, and see to think that the natural thing is therfore to continue being married. I disagree, you sound miserable and frightened, and even though you do love him I would say this sounds like a case where love just isn't enough. Does this relationship, on balance, really make you happy more than it makes you sad/scared/frustrated?
You say you don't know how you, an intelligent woman, ended up here. You are not alone! Many intelligent women end up subject to domestic abuse, gradually accepting things that if they were presented with on a list at the start of the relationship, they would say of course they wouldn't tolerate. I would say don't focus on the part, or on your DH: you can't change either of those (and he won't change, by the way, why should he? I bet he has you doing 99% of house/child/life jobs too, does he? ) The only things you can change are you, and your future.
You texted him that you were considering your relationship. Think about his reply: HE loves you, HE needs your support, HE is busy at work .... It's all about him isn't it? Sounds like he sees you not as WitchWay, but as HIS wife. Maybe he does love you, as he says, but I wouldn't value that sort of love very highly.
Think about your future, and assume while you do it that he won't change from how he is now. Do you want a future with him?
