I think I’m going to call of my wedding that’s a week away....nice comments welcome! Please!

So this is going to be a long one but I seriously need opinions and support from 3rd party people who don’t know us. I’m 23 and he’s 31 we’ve been together since I was 19 and moved in together very quickly into the relationship, we were friends and hung out with other mutual friends (varying in ages from mine to his) for a year before dating. Things were great at first like they always are but in the last year while planning our wedding my eyes have opened up and I’m starting to doubt. I love this man with all my heart, but there’s some things I cant stand that don’t seem to be changing anytime soon. To start off he loves to drink and I don’t drink at all by choice. I don’t mind a social drinker but he heavily drinks almost 3-4 times a week. His job stresses him out (he’s a head chef) and works 15 hour days and never has time for us anymore l and comes homes and drinks most days. Hesnever abusive physically but he comes home and does the same thing: he flips out if I want attention, says he hates me, he doesn’t want to marry, and all other mean things. Then the next day apologizes and we move on. Secondly in the last about 3 months I got really depressed and anxious, not wanting to leave the house or go out or do anything, and he hasn’t helped in bit. I stopped having an appetite so I lost weight which I can’t loose anymore I’m only 4’9” 86 pounds. We barely sleep in the same bed together nightly, and there’s no time spent together or romance it’s so hard. Then about 2 months ago I found out I was pregnant which wasn’t planned and I freaked and stressed about that, and then sadly had a miscarraige. All a few months before the wedding. He was there for me and cried with me in the hospital and we talked about it there, but that’s it then we never talked about it again, but I did and it hurt, a lot. I’m sad I lost my baby. There’s just no care and no love. I had the flu last week and asked him to grab me some dayquil and misc things and he said of course and I call him after an hour to see if he was finding everything okay and he’s at the bar with his friend from work! That was it for me so I called my best friend and she zoomed over to take me to the store since he took my car. Just so many things have added up and I am just miserable. Honestly the only reason I feel like I am here is for financials because he makes more than me right now and if we were to break up I want to stay here I don’t have the option of going home like he does, and I’d need to change my whole work life and financials around which stresses me out. I just don’t feel happy but I have no idea what to do. I’m not myself right now and I’m torn between love and reality of it all. Please give me positive help ladies I seriously need it
