My ex got me pregnant on purpose?

We broke up but the last few times of sex we used condoms ...non broke .... but I have a feeling he poked holes in a condom because one of the condoms were open and he said somethng like it was like that and im not sure if he used it or opened it himself... and he's already abusive and I told him I don't wanna be with him that I wanna move on ... and last night I took a pregnancy test and it came up positive ... and I let him know and he said to basically go **** myself... I live with my family and I go to school and there's no way I can afford a baby ...... and I don't want this guy to ruin my life... what would u do??
