Have Bad Self Esteem, Depressed. Partner Ignorant And Cynical. What Should Help Me?

What do i do? my parents think i am in an abusive relationship and want me to seek help, but i don t know what to do. i recently started getting worried about myself as i now have zero self esteem, am always upset, and i may even admit to being a little depressed. i love my boyfriend dearly, and don t want to be without him. i don t know why because i don t receive any attention from him, any compliments, care or concerns...nothing for that matter. he gets angry over everything and shows his temper to me. nothing i say is ever right, and he always has to win, making everything a debate. he constantly criticizes what i wear saying i look slutty, when i actually look nice. i go out of my way to try to win attention from him, and end up getting really upset and hurt. this always results in an argument because i m being a crazy bitch and he doesn t want to deal with it. i always get conned into spending money on him, and when he finally treats me to something its a huge ordeal, and I m made to feel bad about him spending money on me. if i try to hug him or kiss him he says im smothering him and being clinging. he has gone thru my phone before and started arguments about ppl i was texting, even tho i pour my heart out to him and tell him i only have eyes for him. the list could go on and on, and the more i think about this, the more sick it makes me feel...
