Don't get just factual then, use emotive language and bring it back to you.
I.e: I feel
Just be honest most importantly. Re-iterate why you want this baby and how it is not to spite him or to take money from him. Don't try and trick him into wanting this, it won't work out the way your want it to if you do.
I support your choice no matter what and it sounds like you've already made up your mind. Would you keep this baby, even if he leaves? Honestly, you already know his feelings on the matter so it's not a case of keeping the baby (you've already made up your mind), it's case of preparing your self to leave. He might change his mind but it doesn't sound that way.
