This guy may not be entirely sure about whether he wants to go on that date with you.
If he was the one that cancelled the prior date, there is a good chance that he may not have even wanted to go on it.
Regardless of what he told you in terms of why he couldn’t make it to the date, he may actually not have truly wanted to go.
However, he may be continuing to text but not reschedule that cancelled date because he is unwilling to let go of the prospect of going out on a date with you entirely.
This may depend on how much effort you have both been putting into this, as well as the weight of expectations that you may have of him, that may or may not be premature.
If you are wondering about whether you are expecting too much from this guy, it may be because it feels as though you are the one who is putting out the majority of the effort in this interaction.
Perhaps you are the one who tends to plan out the dates.
This guy may not be entirely sure about whether he wants to go on that date with you.
