Bipolar behavior ?

well like every relatioinship, everything starts off good, then all the sudden there were a couple times where he wanted to break up. we always got back together and well now im months pregnant. We lived together for a while and at times it was good then all the sudden he would change and would act like a complete a**! he would make me cry at night saying he was better than me and why was he with me if i couldnt do what he expected like cook. he made me feel so bad to a point where i left him and came to live with my parents. when i came back with parents he would come by often to check up on me because my parents would tell them that they sensed me a bit depressed. a couple times he came to visit me he would get into big arguments with me and my mother. my mom would ask him if he had any feelings towards me and our unborn baby and all that he would answer was i care about the baby and respect your daughter. i expected to hear i love both of them but i guess not. now were at a point where i cant see him or talk to him because he tells me he loves me then takes it back and calls me an easy who*. i know im not but i just cant stand that he says he loves me, changes his mind. then says he loves me again. i dont know what the exact symptoms of bipolar disorder are but i know hes had problems before in a previous relation and now hes not able to see his child from that realtion anymore. im due in a couple of weeks and this just bugs me because i dont even know if i should let them be there for the birth or not? he treated me like poo then tries to be all sweet saying he'll change then act the same. is this normal guy behavior or bipolar disorder? he only cares about himself and when we were together he wasn't working now that were not speaking he works and spends his money on dumb things like another sports car instead of thinking about me or baby. so financially he not responsible, he makes rash decisions and constantly changes his mind. he wanted sex everyday sometimes three times. he wasn't much energetic since he spent alot of time playing dumb video games, and didn't sleep that much.. umm like i said i dont know the exact symptoms but i just wanna know is this normal guy behavior or bipolar disorder?
