Need advice😭

My boyfriend and I were talking last night about how we didn't want anymore kids...

but then he told me he didn't even want this one at first I thought he was joking cause he usually jokes to make me mad but he was serious he said" I told you I didn't want any kids". "But it happened we are just going to have to deal with it and raise him" ......He Never told me he didn't want kids and I think he doesn't want to marry me either he'll just say "when the time is right"

And I feel like it all makes sense how he just wants to spend money on new BMW we can't afford and new shoes and he hasn't bought the big stuff we need for the baby.. what should I do?
