Sorry, Sadtiger, but your husband has no consideration for your feelings, and has no desire to be intimate with you.
The word "intimate" does not just mean "physically or sexually intimate." There is emotional intimacy too. I don‘t think your husband either wants that....or probably can‘t handle it.
Before he took this job, was he cuddly & romantic? Did he take time to engage in foreplay to arouse you? Did he hold you after making love, and engage in pillow talk with you?
If he didn‘t before, why would you expect him to be any different now?
If he DID before, and he isn‘t doing those things now, then something in him has changed.
My now ex-husband would do the foreplay thing, but if he didn‘t have to, he‘d rather skip it. He was NOT into cuddling afterwards, in fact he HATED being touched after sex. He could fuck me, but he had major problems with emotional intimacy. He also looked at a lot of porn, and had done so since he was very young (like 10 y.o. or something).
About your husband......My gut tells me....porn. You say he talks to you like you‘re a porn star, has sex with you, then either turns away or gets up. It sounds to me like he can only think of you as a sexual object, and looking at a lot of porn can change a man that way.
He‘s away from you a lot, my guess is that he has a porn fantasy sexual world that you are not a part of. When people (not just men) view a lot of porn, it can really change them. Read this article & check out the website:

Can you snoop around & find out if he has a porn collection on his computer, or if he‘s been calling sex chat lines....or worse.....hookers?
If I were you, I would NOT have sex with him until you investigate this thoroughly. At least not unprotected sex. Be safe & protect yourself.
I know I might be jumping to conclusions, but many of us have seen this type of behavior before & have experienced the negative consequences of it....Trust your OWN gut. What does it tell you?
Good luck,
UB
