I have a few close friends and relatives in situations where they've been in long term relationships, communicated they want to get engaged to their SOs by a certain point in their lives, and now are feeling anxious or depressed because their SOs haven't seemed to do anything.
I was with FI for 5 years before we got engaged. I certainly expressed to him somewhere early along the line that if I was going to plan my life with somebody, I expected marriage to be in the equation. However, I never gave an ultimatum that I needed a proposal "by the time I'm x age" or "after we've been dating x years". I generally feel like that is a bad idea, since it may pressure your partner into proposing when they really aren't emotionally ready for it. FI and I arrived at the same emotional place around the same time, thankfully. We didn't have a very traditional proposal, however, so much as a mutual conversation agreeing that we wanted to be married, and were thus engaged.
However, wondering what others' thoughts are, and if you think there is ever a situation in which it is right to put your foot down and basically say "You have X amount of time to confirm that you want to marry me, or else I'm walking."
