Bf wants me to have an abortion or morning after pill and I don't want too!

My bf and I just recently found out after not long of dating that I'm pregnant and he wants me to get an abortion... I don't believe in it, he doesn't want it at all..Tells me we are in not in the position for a child, which we aren't. But why the fuck do I have to be given an ultimatum about what I want to keep?

Opinions please
