TW abortion . Needing advice

So I started having sex with this guy and I am pregnant with his child and I just found out recently . He has made it very clear in the past that he doesn’t want kids and would want me to get an abortion if I got pregnant (I haven’t told him yet ) and I don’t know what to do . I don’t want to ruin his life with a child he doesn’t want and I don’t want to do it alone but I know deep down I can’t go through with an abortion and I would probably regret it . Would you just raise the baby on your own ? We are both 21 by the way . I just have a lot of things to think about and would love some advice thank you
