IDK WHAT TO DO i’ve been crying all day someone pls help

My boyfriend and i have been together for a year on January 22nd 2018. Lately i’ve been having a hard home life.. i always have had a hard home situation but recently it has gotten worse.. I don’t have any friends because they all use me and stuff so i don’t talk to friends and cannot talk to my family since we don’t get along. i talk to my boyfriend about everything.. he understands why, and give me advice .. when he gives me advice i always tell him it’s dumb and just turn it into more of a negative situation.. i’m always negative constantly .. my family went super down hill 3 months into our relationship and that is when mine and my boyfriends problems began.. it’s gotten worse and worse.. he has talked to me multiple times about how i hurt his feelings and about how he’s feeling over whelmed and can’t be putting 95% into the relationship anymore.. i promised i would change for me and for us.. i didn’t keep my promise.. last night he’s finally done.. he has told me it’s his literal last straw.. he isn’t sure he wants to be with me anymore, he doesn’t know what to do.. he said he doesn’t think it’ll work out long term anymore due to all of this.. he said if something doesn’t change fast it’s done cuz we are failing fast.. he said he still loves me but he can’t do this much longer.. he seems like he has no hope.. i’m scared.. he says this is my last chance.. i think hes going to break up with me.. after the phone call of all this last night.. the texts went back to normal happy joking around and making fun of eachother.. like nothing happened i’m over thinking that he’s being dry.. what’s your advice ? i’m scared (i’m going to his house friday-sunday)
