Feel alone

So this is my first time being pregnant and I thought it was going to bring me and my baby's father closer but it hasn't. He works at a bullshit ass job (only 2-4 hours a day), I can't work cause I'm an EMT and I can't do heavy lifting anymore so I'm home all day in pain, trying to deal with this HG and on top of that I found out yesterday I'm having issues with my gallbladder. I thought he was going to have some sort of sympathy but I was wrong. He comes home from work, leaves, comes back, watches tv with me for like 2 minutes then leaves again. Now how am I supposed to feel about that? He leaves me here home alone for him to go smoke and chill with God knows who and I'm here like a dumb ass. I wanna leave so bad, at least a day out with some friends or family but it sucks that I don't even have that. I feel alone with no one to talk to.
