2nd trimester venting

i dont understand this my husband was so excited when we found out i was pregnate, i was only 4 aweeks pregnate an he told everyone, i asked him not to being that it is personal an what if we lost it, it seems to me when it comes to the fun stuff..braging,touching the bump, going through names he's all for it, when it comes to understanding how i feel emotionally an with my body he just says relax.. do you know how annoying that is..relax, relax, relax...SHOVE IT... any ways im now 4 mons pregnate im showing a bump im a basket case im tired still kind of sick, however i take care of our 4 yr old i take care of our home..cooking, cleaning, tubby time, bed time, play time, reading books, preparing our 4 yr old for a new comer. When i need help im scared to ask, when im hungary or thirty im scared to ask, i just do everything myself, he is not the father of my 4 yr to old an with that pregnacy i did everthing myself, i was alone, so i do agree it is a new feeling having a partner with me, but i wish he would ask if i need anything, if i say im thirsty ask to get me something, take the 4 yr old to the park...something..... theres no doubt that he loves us, however he puts himslf first. an im starting to think id be better off alone..... i try to express my feelings but he argues, i stay quiet to just get over it myself neither work... i want to have a partner in this this without me having to ask..is that possible....
