Yated Shidduch Forum 6/18/21: No Reason to Say No, but Also No Reason to Say Yes. What Now?

Question:
I’ve gone out with a boy a few times. He’s nice and we have interesting conversations, but I feel so stressed when I think about going further, because I’m just not sure if he is someone I want to marry. There is nothing wrong with him, per se, and I don’t even know why I feel this way. Do I keep saying yes just because there is no concrete reason to say no? If so, at what point is not having a reason to say no not a good enough of a reason to say yes?
