I'm Seeing a Pattern in Engagements

Anyone else seeing this lately a lot?

Guy is going out with a girl who is either out of his league or at the top of his range. Guy is insecure about his long term prospects with said girl. Guy proposes way earlier than he should in an attempt to "trap" the girl into staying with him. Proposal is super elaborate and super public (asking at a ball game etc.) so the girl feels obligated into saying yes.

I have a coworker who is apparently going to start a long distance marriage. Wtf is that? Wouldn't you try date a while longer and only get married when you have everything figured out 100%?
