Since I’m married, my opinion may not count, but given the fact that my spouse and kids are all that makes my life (work, struggles, ect) worth living, I would say that if I could not find the “women of my dreams” after a while (say, 5-6 years of consistant looking) I would give my ideas of what I need to be looking for a serious re-think.
I don’t say, you need to “settle”; you just need to be realistic of what a person can be and what you really NEED in a spouse.
But to stay alone? No, life is too tough to face it alone.
