Is he showing signs of abusive nature

Ok I have this boyfriend and we have been dating for a year and 1/2 … I recently got pregnant with his baby …I love him with all my heart but sometimes I just cant stand how he treats me or my family for example when I am with my aunt he calls her cell phone and if she just happens to accidently miss his phone call he starts going off on her saying well you need to tell me if my girl is with you or not! And also the other day I went with her to her dads house so she can cook supper for her dad and my uncle (they work together and come to the house for supper) and we were really busy cooking and my aunt had her phone on silent and why we were cooking he was calling and texting and everything else even though he knew we were busy and I would call him back then he wants to get rude with her in text messages and then yell at me for not calling him right back or answering the calls or texting back even though he was told I was busy helping her cook and clean but anyways that was an example moving on …also when I go places with out calling him and telling him and he just happens to call me he get pissed off cus he has no clue where I am … And we always get in to a big fight because of this .. But then again he has a cell and most of the time I cant even get a hold of him … But when I ask him where he has been and why he didnt answer his phone he gets all mad and goes off on me … He has cheated on me before and I just wonder sometimes if he is doing it again … When we talk at night he always tells me well I am going to go to bed and it will only be like 9 but yet he wont even wake up till 4pm..or so he says …and when we lived together he would stay up all night and still be able to get up early with me when I left for school … But when I moved back in with my mom all of a sudden he has changed his ways. he is always needing to do something when I know damn well he just dont want to talk to me … Plus he always blames me for everything and puts me down a lot of the time. And when he is pissed off at me he acts like he wants to be with me just not like what he us to … He says he loves and cries everytime I say we need a break …and he always tells me he couldnt live with out me but if it was true then why does he do the things he does …he says he loves me and only wants to be with me … Please tell me what you think and what I should do … From a worried mom!!
