He is four and does nothing but cry and act like a baby

He tells me he doesn't want me to have his sibling his mom and dad should 

He doesn't listen to a damn word anyone says and if you raise your voice he crys for hours 

If he doesn't get his way he throws himself down and says he hates you and your mad at him 

If I tell him no he screams and crys till my boyfriend gives him what he wants even after he was told no 

He is a lying spoiled brat 

I punish him for the things he has done wrong 

Examples 

Back talking 

Throwing things 

Hitting 

Throwing tantrums 

Misbehaving to extremes 

Fighting 

Name calling 

But yet when his grandfather comes around and sees me yell at him and then put him in time out I'm the bad guy if I don't punish him I'm the bad guy 

I only ever put him in time out I've never put my hands on him to whoop him even thou that's what he really needs in my opinion  is a good old fashioned ass whopping everytime he acts up and acts out like that 

What really gets me is the non stoping crying for no reason 

We go out and he falls asleep in the cry so we wake him up and make him get inside and to go pee and change before bed he stands there and crys for 20 mins after we have told him to go potty he won't go until his father goes in there and stands beside him to pee then is another hour of crying while we put him in his bed and get him changed because he wants to sleep in daddy's bed  then every hour on the hour he try's to get in the bed with me and my boyfriend while crying and screaming and that means he has to climb over me to get to his father of course I wake up tell him absolutely not and make him get back in his bed (boyfriend still sleeping even with his Son screaming) he then proceeds to try to hit me and kick me and me being pregnant get fed up with him constantly trying but to hit me and kick me in the abdomen tell him I'm going to whoop his ass if he doesn't quit and that makes him scream more so I finally get sick of it and wake his father up who gets up and baby's him 

Now I will not deal with this when mine and my boyfriends child gets here.. I don't even want his son around the baby for the fear of him hurting the baby and I get so judge for saying that but I don't care I'm not going to wake up every 15 mins to a screaming four year old after waking up to a screaming newborn who woke up because the screaming four year old  And my boyfriend has already said since he works mornings I'll be getting up with the baby during the night .. Fine then I don't want YOUR son there till he quits his shit 😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡 I would like to add these pictures of bruises I have gotten on me from him 

Here is a few edits -I have read all the comments a few( more like a lot ) of you feel it necessary to judge me and tell me I'm a horrible person or a hateful person because of how my wording is.. Yes I am at my wits end with this little boy I was emotional and crying and so fed up with it when I first wrote this I would like to add that I don't really hate him I am over and hating the way he acts  everything was fine till he started visiting his mother again in October  she had gotten him takin away by the state in May after she had got in trouble with drugs and impaired driving while he was in the car they have been separated for almost two years and I have been in his life for almost one so yes I have been around a while and not going anywhere I am not "jealous " of him I don't know where some of you have got that I'm over how he is spoiled never told no and if I say no he throws a fit till his father gives it to him there's no jealousy there it's more like pissed with a passion if you want to know more please ask and as I read thru them I will answer them back here for I don't need your negativey -
