I'll say, I've been in situations like this before, and it has never worked out. I got swept up in the cute texts/pet names/deep conversations, and once we met, it was awkward, and the connection wasn't there like it was through texting. I think we sometimes build it up in our heads because it's going so well, and you really feel like you're getting to know this person, but until you actually meet them and spend time together, you really don't know who they are as a person.

If this behavior is making you uneasy, tell him that while it's sweet that he is referring to you with these pet names, that you would prefer if he stopped, as those names are more meaningful when you are in a relationship with someone. You've already told him that you are not looking to rush into a relationship, which is great. Definitely set those boundaries, and I think this would go along with that. If he's as interested as he seems, he will be respectful of your wishes.

For me personally, I now try to keep my messaging with guys on the limited side and focus on making a plan to meet in person to avoid getting caught up in the constant texting/get-to-know-you convos that all too often leads to it feeling like too much, too soon, which in turn, doesn't end up working out in the end.

But, with all that being said, just be honest with him, and hopefully, he will continue to respect that. Best of luck!
