Frankly, at 47, i wouldn't want to marry for the sake of being able to live together for the rest of our life, and especially after getting to know each other again for about a year or so only.
Why the rush? Career, Age, no kids, health, everything is ok. Why can't we just stay together and make the honeymoon longer and if after ten years, fifteen?, and if everything is really fine, then you marry.
Can roughly characterize her, and I think she is a difficult person to live with for the hardheaded guys, unless one really give way to her all the times and let her be the driver in the relationship. Nice lady she is, but going to be tough for him
