Does this sound weird to you?

My ex is saying he wants us to get back together. Hes being saying it for a few weeks now. I want to too, we never broke up because of anything bad and it's worth giving it a try as I'm 20 weeks pregnant with his baby. He's saying not right now though, he wants to wait until he's got his job, which I know he's getting in December, so we can get our own flat and do it all the proper way and settle down. We've never had that before we've always lived with our parents. Until then we carry on as we were seeing each other and talking and working on past issues so then when it comes to us getting back together there will be no problems. I don't know if this seems weird or I'm just being paranoid? Like why does he want to wait? Am I being paranoid or does this sound a bit strange?
