I found the one...how long should I wait? I'm not getting any younger....?

I've had my share of long term boyfriends, been married, had a child, divorced, then a few more long-term relationships, turned down several proposals, then I met the perfect man (for me anyways-nobody's perfect). Now things are more complicated, both divorced each with a daughter, and we recently moved in together. I don't pressure him or ask about marriage because he was married to an older woman he met in college for 12 years (and raised her 2 children from her previous marriage). I made sure early on that he wanted to get re-married because I felt myself falling hard for him. I am actually against living together without being married, but in our situation I felt like I needed to find out faster if this was really gonna work. We've had some small speed bumps, but overall it's been fantastic! I've never been happier! Being a relationship pessimist is my specialty....I've never allowed myself to be mushy gushy in love until now. But here I am with the big 40 just out of reach (but looming). My parents adore him (they have never liked anyone- ever) and mom says, "What are you waiting for? You're not getting any younger!" My friends say, "What's the hold up? He is perfect for you!" Call me old fashioned, but I think I deserve that romantic proposal that I've always dreamed of- and one I can say YES to! I don't want to ruin it potentially by talking about marriage, etc all the time. It's been a whirlwind of a year but I've never been more certain. I do worry about what God thinks of this, and I want to make it right. How long do I wait?
