You are right, Valexand, that, NO, it doesn't happen for all of us.
But I hope you won't consign yourself to being as your aunt was...
At your age (and I do remember how I felt at age 30), it can seem there are no options. but for you, there are, there really are many options out there!
Consider this...There really are much worse things than being alone, like being with someone you don't really love (for 20+ years as I did while raising my daughter). Enjoy your freedon, your independence, your intelligence (which is so obvious from your writing!).
I really like you, and feel toward you, and comment to you as I would my own daughter who is your age.
Love
Patty
