He doesnt know what he wants....

my boyfriend said he didn't want to get married anymore because he was having doubts but he still wants to be with me. We got pregnant and he was all for it and now he doesn't know if he wants it anymore. he thinks we're not ready and he wants to get an abortion even though that's not what I want. and he also said if I wanted to give it up he'd be okay with that too. I'm 8w2d now and I'm only 19 and he's 27 I can't afford it by myself I'm just so heartbroken. idk if I'll ever have a kid again if this is what my options are.
