Guy I’ve been seeing rejected seeing each other tonight because he “has to walk the dog early” tomorrow. Is it doomed?

For a little more context. Have been on two dates and talking consistently with a guy who has been nothing but green flags thus far. We did sleep together on the second date, which for me just felt right and I don’t at all regret it. This was last weekend. We’ve not seen each other since, but have spoken consistently as I said and we were unable to make plans to see other this week due to prior commitments on both sides (it’s just that time of year) however have loose plans for next Saturday night.

Now. Tonight he cancelled his original plans and said he was staying at home (Friday night here in Australia). We got talking and the talk got steamy and I offered to go over his place since it was still early. His response was that he has to get up early to walk his dog in the morning, so we probably shouldn’t. Which just felt like a total cop-out.

Does this seem like it’s over? Or am I overthinking things? I like being told the truth, so if he’s not interested anymore or just needs time to himself etc. I’d rather he just say. But I am really in my head about it.

Any insights to help a girl out?
