im not happy in my marriage & scared!

My husband barely has time for me its cuz of work, plus lately im having trust issues (he's clean ) but I cannot convince my mind ! I feel soo damn alone! He has always been horrible with intimacy! No cuddling , or touching or kissing! Just sex , that's all he wants ! I feel soo damn unimportant and useless. & don't suggest talking about it with him ! Cuz i have a million times ! He blames me ! He says i have a mood problem & he can't deal with my mood swings! He says that yoy always want to be pampered n all & I cannot do that ... he's soo mean n get mad whenever i tell him how i feel! We have a 14month old baby boy together! I just want a separation! I want out to be honest! But where i come from (family n religion) .. it ll be next to impossible .. families are involved & its complicated! What should i do? Im sooo damn unhappy!
