Mother problems

Lizbeth
I'm 17 and pregnant. My mom wants me to get an abortion. There's been a time where she accepted that I'm pregnant but all of a sudden she ask me do you really want to have that baby? Time is flying and you can still get an abortion. 
It hurts me when she says that. She has been treating me differently since i told her i was pregnant. 
Either i get an abortion and make her happy and my boyfriend breaks up with me. Or have the baby and i wont have a good relationship with my mother. She took away my car just to make my life more difficult. We are a wealthy family so my thought everytime she does something is so i can a have difficult time. My older brother is also having a baby and whatever he needed she'd give him. He got a new phone and my mom told him to stop paying the car so she basically gave a car to him (he's the bad one he's ungrateful he's been in prison for drugs and she still gives him everything). All my life has been about making her happy and this happend and its like i have done something worse. I need advice on wether i should get an abortion some tips on what i should do. I don't know what i want. No rude comments. I think i have gotten enough rudeness from my own mother..
