I get asked this question MORE than I can even count. My answer is always whenever you feel it in your heart, it’s right.
There is nothing wrong with wanting to be exclusive with someone even after one date. If that is the season of life you are in and you don’t want to date around, you shouldn’t have any worry bringing it up in conversation.
If the person you are dating isn’t on the same page that’s something you’d rather know sooner than later.
With that being said, make sure you really are looking at this person and asking yourself what it is about them that is drawing you to them. Really look at their character and your chemistry versus what they are on paper. Really make sure this is someone you want to pursue exclusively because don’t ever forget YOU ARE A PRIZE! YOUR TIME IS PRECIOUS! And THEY ARE JUST AS LUCKY TO BE DATING YOU!
That is all ☺
