sleeping man and health rant

so my boyfriend has always done this thing where he sits on the recliner to play his game but ends up falling asleep. he can fall asleep within seconds and sleeps allot. besides that there are other medical concerns he won't get checked out. anyways i find it hard to sleep without him or i can't sleep knowing hes on the couch when he should be in bed especially when he has work or we have to get up early. the thought of it being uncomfortable keeps me up. like he'll even fall asleep on the toilet which leads to him being late for many things. i stay up til he comes to bed and i wake up when i don't feel him next to me. its weird but somehow it happens. ill go try and wake him up but hes stubborn and being 37 weeks pregnant i can't really pull him up even though he on a recliner that rocks like i used to pull his arms and hed wake up. he doesn't really respond when im verbal. soon we'll have a baby and i feel like ill be alone. he sleeps so much and i don't think ill be able to stay up just to make sure he comes to bed. his cousin which lives here too told him things need to change and that he shouldn't depend on me that i should be able to depend on him. honestly i feel like hes right. financially i depend on him but besides that im on my own.im caring more about him then he does himself which isnt fair yet its just how it is. soon ill be caring for 3 instead of 3 and im most likely to be mentally drained. he needs to get his health in check. from sleeping to much and being obese also his lack of wanting to do anything . we stay home most days that he doesn't work we never go out unless its to the grocery store. hes so unmotivated which is killing me because he wasn't like this before. we would go out and have sex now im lucky to even get a hug . i care about him but things need to change like i feel like im watching him slip away and its scary thinking that with his health he might not be here long enough to see his son grow into a man. he doesn't see things how i do im worried about him. he has 2 kids now and hes not even active. his daughter doesn't live with us but if she's ever allowed to come stay for several weeks again i dont think he would be able to keep up . a toddler and a baby are allot i know from helping raise my niece and nephew if he doesn't get this in order i don't know what to do. i can't help someone that doesnt want help. i can't force s grown man to do something. hes 12 years older than me yet im more mature in some aspects. i need to relax but i can't. he seems to do the relaxing for us both and i do the rest.
