Commitment: Opinions?

Hello everyone! I just wanted some tips or opinions on how to react or deal with an SO who isn't really the type of person who wants to marry but you absolutely are? My boyfriend who I've been with for 3yrs + isn't the type of guy who thinks marriage is necessary and really isn't into it, also he constantly talks about how great it will be to have a place to ourselves and have a family. It makes me a bit sad sometimes because I'd really like to marry soon but he's just not feeling it. I'm not pushing him towards anything he doesn't want to do, I just keep my feelings on the inside. So I was wondering, are any of you going through the same and if so, any tips on how to deal with it?
