Hello WelshyAndProud & Welcome
Was that your first date, or have you been going out for a while?
How long have you known each other?
He has texted you twice, but how many times have you texted him?
Did his texts sound as if he had enjoyed being with you?
Could he, perhaps, be feeling equally doubtful about what to do next ~ especially since you are going away?
Could you contact him and ask of you could meet up again ~ even if only briefly ~ before you go?
