In all honesty from a guy's point of view, there's no need to press right now. You're engaged, so it's going to happen sooner or later, and it's only been 2 months! It's still probably very new to him and sometimes guys need a longer time to adjust to an arrangement such as this. I can tell you that if you do start pressing him, he's more than likely going to get mad.
My wife and I arranged to move in together before our wedding, and it was 100 times easier to do it before rather than after. I'd ease up for a couple of months, then start the press again.
Enjoy your engagement while you can. Once marriage comes, then kids, you lose a ton of the time you had for yourselves. Take advantage.
