I feel.....unhappy...?

I guess I just feel so unhappy in my relationship or maybe my life? I’m 27 weeks pregnant and currently live with my boyfriend (23) and his parents because we can’t afford a place to live on our own cause I’m the only one working (I’m 22). I’m tired of being trapped in his room all the time because this isn’t my house so I don’t feel comfortable to do things like clean or put my own food in the pantry because it’s not my house so I don’t wanna take up space. So I’ve been living off fast food and snacks for months. (Even tho his parents are super sweet and tell me to eat whatever but I don’t wanna spike their grocery bill when they already have 3 kids, two of which are adults and could pay for things but don’t and his parent don’t ask them to). And all he does is play video games. Thats it! 99% of the time he acts like going out with me to do errands or just do things is such a chore and he won’t really do more than 2 things with me. Like if I have a full day of things planned he’s like “you know you can do things without me right?”. Like yeah sure I could but I mean were gonna be a family supposedly wouldn’t you maybe like to go do things? And even when he agrees its always got such an edge to it like he doesn’t want to but will to appease me. He never just offers or suggests we do things. And he doesn’t give a flying fuck about getting a job. He’s had 6 months to get a job and I finally got him to apply at my work place because it’s easy work and he’s more likely to stay. But the first site he got there and left because my abusive ex apparently was gonna be the one to train him (that one I don’t blame him for he would have gotten into a fight and gotten arrested). BUT the 2nd site they tried putting him on they turned down because the site doesn’t allow you to do anything but sit in a chair and stare. Like you can’t have paper or food or phones or books or anything at all. You sit in a chair, see maybe 10 people in your 12 hour shift, and stare off into space. And have to pray someone comes thru with a yellow lanyard and has time to let you pee or else you can’t go to the bathroom. His reasoning was that he wanted to be able to do school work....even tho he only goes to class on Monday and has 6 other days to do said school work. I mean yeah the place sucks but you’re about to have a kid in 3mo if he’s not early and I’m the only one working towards getting a place to live. I just feel so stressed and unhappy cause he’s not a bad person. He loves me and gives me back massages in the am when I get off work and grabs snacks when I need him to and if I ask for cuddles I usually get them (even if I have to watch for a video game match to end) and he’s used his credit card to help get me out of some tough spots I wouldn’t have been able to get out of myself. But I’m still just so unhappy and I don’t know why

Aaaannndddd as I type this he asked me to put the clothes from the washer into the dryer because he’s “trying to get his sleep schedule on track” cause he starts school next week (it’s noon here, shouldn’t that mean he needs to be awake???). I don’t care about the chore cause he always does the laundry (like....one load every 2 weeks cause thats what we go through) but just the fact that I reminded him it was there and he wont get out of bed. He’s been in bed all weekend! He slept from midnight till 8pm Friday when I stayed up 24 hours cause of Gabriel (the baby in my belly) and him making the bed uncomfy! I just wanna cry. I need a margarita and I can’t have one!
