pregnant....

So I just found out Sunday that I'm pregnant and I told my bf and he got so mad and says that he doesn't kno if he wants to be with me anymore because he doesn't want another kid (he already has two) and he's also mad because I won't get an abortion because I'm pro life. But I feel that he's not taking how I feel about this in to consideration because this child will be my 4th kid...I just am needing support and he's not giving me any and idk what to do because despite everything I love him....
