Need some advice please

We’ve been talking consistently for about a month now, just going with the flow, except for some weekends when he’s off doing something with his “buddies”, who knows. I’ve been only seeing him, and he’s claiming that he’s only been seeing me. We try to see each other once a week. Our chemistry and sexual attraction is intense in person, so I have no complaints there. There are days when he sounds interested in text, but some days when he doesn’t and I wonder if I should even bother? But then that question goes out the door when I usually try to cut him out by not responding to his last text and he would keep reaching out to me to see if I am still “alive”. Then I would feel bad and then the flame would reignite again. Fast forward to today. I was sexting him crazily, even took a sexy pic (w/o my face & girly parts in it of course) and he usually heart reacts my pics/vids, but didn’t this time, and although he did respond (asking to see my kitty), I started wondering if the pics were good at all because not soon after I sent him pics of my bike that came in and he heart reacted both of them immediately! I tried not to think about it too much. As I was installing my bike in the nude, I had doordash and didn’t realize the guy was outside my apt complex so I threw whatever I could find on me w/o any bra on underneath and the door dasher was flirting with me but I just thought it was a funny situation because it reminded me of what happened last year. So I told him in a humorous way about what took place and he responds with a “lol, okay?”

I didn’t think he would take it that way and my embarrassment took over because he probably thought I said that to make him jealous when that wasn’t my intention. I’ve always made jokes about stuff like that…

I haven’t responded at all since the afternoon and I don’t know if he will reach out tomorrow or the next like he’s done so before.

He’s the only guy I’ve been talking to since coming back into the dating scene after 2 years. He knows my intentions as I’m looking for something long term but open to going with the flow and I know what his intentions are since he had flat out told me he isn’t looking for an emotional connection because he is leaving the states next year to go back home for a year or two, and this was after 3 weeks in of us talking. And I know it’s only been a month, but I won’t deny that I really do like him… a small piece of me is hoping that he would come around but I highly doubt that.

Aside from our super embarrassing exchange today, our “situationship” and conversations have been amazing. But at the same time, when I get these types of responses/reactions I tend to shut down and overthink negatively.

Can I get some advice please? Should I bother at all? And if yes, how should I respond back to that?

I just feel completely embarrassed.

TLDR; great guy I’ve only been seeing for a month made me feel embarrassed over our communication today. Wondering if I’m overreacting as well or if I should just reach out to him?
