Reply To: mixed emotions right before getting engaged

This is not something I have experience with yet. BUT, maybe, you can ask yourself, “If I never saw this person again, how would I feel? Would I be relieved if I chose not to get engaged?”
If the answer worries you, I would tell you to speak to someone older and wiser, and not just one, but a FEW people who are older and wiser.
Then you need to compare answers and listen to your inner gut feeling (this is even more important).
Not everyone who is old is wise, so be very careful.
