@brotherofurs……….
Your feeling is not that unusual, voicing it in a frum forum is.
I am a lawyer who practices a lot of family law. Your expression is a regret often voiced by women coming to me seeking a divorce. They feel they married too young and didn’t sample what was out there. They were pressured to move quickly so a prime catch shouldn’t get away.
That said, there is no way you could date/meet every available young man on the shidduch circuit. BUT, you shouldn’t be forced to make a lifelong decision based on just a few samples.
It’s one thing to have buyer’s regret when you aren’t happy with a pair of shoes, a husband is much more difficult to return.
