Iwant to get a divorce been married since jan, 37w pregnant and my husband doesnt have any understanding?

we fuss all the time. i dont need the stress. this will be my second divorce first child. i really unhappy with him when we fuss. i mean we cant go a whole month without fussing. i do love him but it just not worth the fussing. over the smallest stuff. today because i send out a general email updating my address book of a email i been having over 8 years. should i getout now or wait to see if things get better?
