Guy is on vaca for a few days and you aren't together should you hear from him?

there is this guy and we go on dates but we are not in a relationship although we talk pretty often when he is here.

he went on a long weekend on Wednesday and I have not heard from him after he left but he said he will see me when he gets back.

does this mean he doesn't like me?

i mean, we aren't in a relationship. we just went on a date two days before he left.

we've been dating but not serious for a few months already. so this is why I feel like he doesn't really like me.
