Why am I afraid to be single?😥

So me n my bf are in a argument right now.. We've been together for 2 years n 11 months.. This month is our anniversary.. He's 21, I'm 18.. We live with my mom, brother n grandma right now.. But anyways he's mad bc I don't wash his laundry.. I cant always buy food for him.. Bc my job sucks.. So he messaged me saying "I'm just gonna starve myself until I get paid" n I was like "um okay" n he goes "k ima just move out on my own n only feed myself".. N thats where things went down hill so I basically sent him a huge ass paragraph telling him, he knows I'm depressed.. He knows I try my best to look for another job.. He expects my mom to buy him food.. Etc.. N he replied with "just bc you have a mental illness doesnt mean you can slack on life" is what he basically said.. N then he replied with "fuck it im done, I'm moving out by myself" I asked if he loved me n he replied with a blank response..

So I know hes an asshole.. But why am I so scared to be single?

I mean I literally have no friends so I cant go out n do anything..

But I have a guy that wants to date me but I'm to scared to get into another relationship bc what if he tricks me like my current bf did?.. Idk what to do.
