When (and how) do I make my intentions clear about exclusivity, marriage, kids, etc.

I’ve started talking to a guy. I feel like I’ve been taking the lead mostly in our conversations. We’ve only been out one time and have texted and called since then. We are about to go on our second date. I don’t know much about him just yet but he seems level-headed, cool but very focused and goal-driven. I have let him know I’m interested by suggesting the first date. He paid for that date. I offered to pay for the second date which will happen in a few days.

Here’s the thing: most of my relationships (probably all) have been relationships where boundaries and rules (if that’s the right word) were not established. This has led to heartache and confusion for both me and the men I have been with. I want to make my intentions clear:

1. I want to date exclusively at a certain agreed-upon point (or now if he’s ready).

2. I want to be with someone who strongly welcomes marriage.

3. I want to be with someone who wants to have kids. (Whatever number of kids we can AFFORD to have lol).

I have never really had these talks with ppl at the beginning or have not been very up-front about my feelings at first out of fear of losing the person and because I would be very shy. Now, I feel like I can say these things with less fear because I just don’t want to waste my time or anyone else’s time.

How can I state these intentions without coming off as a “diva” or controlling? Of course, I’m not going to say them like I’m trying to make a business deal lol. Are these intentions good to bring up on the second date. Should I wait a bit longer.

I am late 20s and he is late 30s.
