7 months pregnant and im losing my mind!! ladies please help?

hi ladies..i have been dealing with alot of depression and saddness because of my pregnancy..but its mainly coming from my babys fathers direction...it seemed like before i got pregnant everything was good and he kept pressuring me for a baby..and now that i am pregnant hes been treating me like crap..we have been together for almost 3 years and i dont know what to do..i really love this man and really want it to work..but i really just dont understand where did we go wrong..i blame my self for everything and i know its not me.i know im very beautiful but now im like really self concious.i dont know if its the hormones or what.it seems like hes more distant from me and its a heartache because i gave him what he wanted and now hes treating me like crap and sometimes it makes me suicidal and not even want to have the baby even though its too late already..please help ladies..any advice would be great..thanks ladies..
