Big changes...yet feeling confilicted.

The bf and I have recently been discussing our future and possibly within the next few months into the next year moving into together. We have known each other for 5 months so far, however we been offical since July.  While early on in our relationship/friendship we had our ups and downs.I am 26 almost 27 in January. He is 25 although was 24 when we met.  However despite his minor disability of AS ( if anyone is unformiliar with this sydrome you can google it) we care so much for each other and so much want a future together. We get along so well and enjoy being together and doing things. I understand we are still learning and growing with each other.  Recently he's been staying over alot more than usual and we have been getting along real well. It's so nice having him around and I love it. As for work we both work two jobs.We work one in the day and one in the evening as well as my bf. I guess my question if we did decide to get a place together in the near future for me is how to tell my family? Needless to say he'd be the second person I lived with (First was my ex fiancee) . However I am catholic and he isn't.  As for my family being strictly religious they wouldn't approve of us living together and getting a place before marriage. I want to be happy and do what i want for our relationship however I don't want to hurt or my family to be upset with me if they found out I had a place with him without being married or engaged. For me it personally doesn't bother me living or being together without a ring or marriage quite yet. Anyone ever been in this situation or can relate? I'd appreciate the feedback!
