A little relationship advice? Please and thank you!

Ok so... I am pregnant and in a relationship with a guy that is not the babies father...(i met him while I was 4 months pregnant) I honestly never thought I was going to be in a relationship like ever again I had a total Mindset that I was going to forever be a single mom and definetly was ok with it! Anyways we haven't been dating long and I'm not sure if it's the pregnancy hormones or if I'm just harsh but. I used to lo e the idea of being touchy feely and whatnot but now it seems since I've been so sick throughout this whole pregnancy I just have moments where I dont want to be touched ... And I'm sorry to say this but I feel like he complains alot and crys alot and I swear his favorite sayings are "what about what I want to do" "no-one cares about my feelings" "you dont ever interact with me"." I always get the shit end of the stick" "it's not fair to me"..... He said all of those to me tonight... Again. I am house setting for a lady and he is here with me.... Anyways I woke up this morning and had morning sickness but wanted to be nice and make breakfast/brunch for him because I had the day off from work so we went to the little store in town and I bought stuff come back and start cooking everything is fine. I feel nauses again after breakfast but manage to keep it down at this point I'm extremely tired and feel like lounging all day so I have my mind set that I'm just going to be on the couch and relax trying to "recover" from puking this morning he can clearly see I dont feel good but is constantly like touching me and putting his mouth near my way and making noises and I hate anything happening to my wars even breathing next to them.. I'm trying to ignore him but dont comment on it.. He continues for the rest of the day I decide to make dinner I cook again and everything is fine then he starts that thing again where he's literally in my face and ears...then he all of a sudden leaves the living room I thought he decided to go to bed after him not coming back after like five minutes so I go into the room and go to get in bed and turn off the light he gets mad at me for turning off the light and me wanting to go too bed... He says he came in here to cry because I wasn't wanting to interact with him... Uses those same lines again and I just say I'm tired I want to sleep I turn off the light and crawl into bed He says "whatever I guess I will go out into the living room and be lonely since you don't want to interact with me" and leaves the room I just lay here then he comes back to the room just to repeat his favorite lines and tell me I'm the one that doesnt care about him blah blah blah turns into an argument and he starts saying he's leaving for the night and whatnot I just don't say anything And shut down (i hate being yelled at and hate being accused of not caring!)... I have done soooo much for him I've stayed at my other families houses and places just for him to be able to spend time with me and make sure he eats everyday and can shower places and I give him money from my small paychecks I get weekly so he at least has some sort of money... I would have him live with me if I could but I cant because I only have a room I'm my aunt and uncle's house that I pay rent for and they dont allow anyone that isn't family over... It sucks ! But I'm working on my own place hopefully will have it right before the baby is here or very shortly after! Anyways I am also constantly with him like always. He even sometimes Waite s around town while I'm at work. (i only work three days a week and don't have set hours since I'm a dog groomer) I pay $200 a month for where I "live" and have been there maybe 5. Random days this whole month... I've been with him every other! Am I in the wrong??? What should I do about everything? I'm just not sure what to do....
