Living with abuse

Hello. My name is Katie, and I'm extremely lost about what to do about my relationship. I've been living with my boyfriend for a few months now and we just got our first apartment together. For a few months I've been noticing many red flags in the relationship, most of which I believe are abusive behaviors/tendencies. Some of the things he does make me feel like he doesn't care about my feelings. He belittles my feelings and doesn't care that he hurts me. He threatens to leave me when I tell him that I'm not happy with the relationship but I'm too scared to leave him, because I can't handle being alone. He expects me to do everything for him but won't do anything for me in return. The only things he'll do for me are things that I have to ask for multiple times, and it's simple things like doing laundry or cleaning up after himself. He tells me things that hurt me when he's angry and never apologies for it despite seeing how badly I'm hurt by them. He's controlling and manipulative. I'm extremely hurt by him almost every day but I don't have the strength to do anything about it. It's gotten to the point that I've had urges to fall back into self harm because he makes me hate myself so much. When I came to him about feeling suicidal he shrugged it off and basically ignored it. I feel stuck. All my friends and family tell me I shouldn't be with him and I believe them, but I'm too scared to leave.
