Told guy I wanna have over I have the place to myself he said he’d let me know?

My ex roommate who I hooked up with told me he wanted to continue, so I told him he could come over this past weekend or this week. This is what he said: not sure what my plan is for the week but will let you know. Is this him blowing me off? I just liked the message didn’t respond. I was thinking of mentioning that I’m leaving for a trip to Europe to see if that starts something but just don’t want to get in the way of the situation. Thoughts?
