My SO and I recently went though this. We even went as far as to get pre-approved for a home-loan (something you might want to look into - it is easier for someone to take you seriously if you already know how much you can spend, etc.) but in the end we decided that 30 years is a long time, it is a commitment we would rather not make unless married (we have been together going on 3 years now, and have known each other for 5....still decided to be married first)
It is, ultimately up to you, but I will say this - you should not look at getting married a business deal. "Can I get tax breaks if we're married." Shouldn't even be a factor when choosing to spend your life with someone. It should just be an extra.
