What to say when he says he's not sure if he's attracted enough

When he says he's not sure, he's already made a choice. He's chosen to tell you rather than move forward, which means either he's keeping you as a backup option or he's being honest that the spark isn't there. Neither of those is actually uncertain. Uncertainty is what he feels before the date. After spending time with you, if he wanted you, he would know.

This statement usually appears after he's had enough time to know. The timing matters. If it's week two, he's felt it or he hasn't. If he's still deciding, he's already telling you something. Don't mistake his indecision for an open question that your reply can answer.

You're not trying to convince him or explain why he should be attracted to you. That's a losing game. Instead, your reply does two things. It acknowledges what he said without fighting it, and it makes clear that you need someone who is sure about you. The move is to be direct and brief. Say something like "I appreciate you being honest, but I need someone who knows they want me. Good luck out there." or similar.

This isn't cold or aggressive. It's just you refusing to sit in his uncertainty. It also gives him a moment to feel the consequence of his words. Sometimes guys who say this are testing whether you'll lower your standards. When you don't, the dynamic shifts.

Reply the day you get the message. Waiting makes it look like you're upset or overthinking. A same-day response that's calm and brief actually has more power because it shows you're not emotionally tangled up in his choice. Write it, read it once to make sure it's not mean, then send it.

After you send it, do not look at whether he's read it, do not check if he's typing, do not craft a follow-up in your head. If he messages back trying to keep you on the line, you get to decide if it deserves a response. Often it won't. You've said what needed saying. The ball is in a court you're walking away from.
