Now, this is an interesting question overall, but it may not have much to do with the dentistry.
In my opinion, I believe that sometimes woman gets quagmired in relationships with man for too long, say 3, 4 or even 6 years. I asked them why, and often it is because the status quo is comforting, and they rather just remain in a safe relationship that isn't working out then going out to explore new relationships.
Now, from a man's perspective, the man who has a girlfriend for too long, and yet not commiting to a marriage is being irresponsible and somewhat selfish. They ought to know that there is a limited range to a woman's youth, and that the man shouldn't be with a woman for more than a few years, and not progressing to marriage.
However, if both parties feel like that they are fine with long term relationships that doesn't lead to anything, then that's fine, do whatever they want to do.
My statements may be opnionated, so I apologize beforehand. I do love to hear what you guys have to say though. Prove me wrong.
