i argued with my bf today

So today i had an argument with my boyfriend (we going thru a really rough time). I’ve asked him multiple to sometimes just understand my side and to basically be my shoulder to lean on at time i don’t feel good but everytime he just makes everything revolve around him and just leave me there to cry by myself with nobody to talk to since he mad me cut off all my grin and my family is on a whole other continent. So today we got some really bad news and i asked him to just be there for me which he didn’t he left and hasn’t came back. but i really feel like i need to talk to someone cause all day i just been having bad thoughts and i’m about to just text somebody i used to talk to cause i feel like if i don’t get most of it out it’s not gonna be good but at the same time i don’t wanna do it cause it’s wrong and ik it but i’ve asked him to be there and he just left but yea idk
