How do I get a clearer view of his pov without looking pushy?

I’ve been seeing this guy for around a month. We’ve agreed on the first date that we’d be as honest as possible with each other but also take things as it goes.

We’re getting along pretty well in general. We’re not in the same city but still managed to see each other almost every weekend. I have an anxious avoidant attachment style which makes me overthink everything. I haven’t been in relationship in years bc of anxiety so I really don’t know how to navigate this thing called dating.

Lately it feels to me like he has less interest but sticks as sex is great. I’m not asking to jump into relationship as it scares me anyway. He’s an introvert and I get that but at the same times I’ve learned through therapy that you can’t expect someone to open up when you’re not reciprocating. I feel the need to ask him if his intentions (meeting and getting to know each other in perspective of relationship) remains the same without making it look like it want to force anything on him.
