He may just not have time to talk to you - it's the weekend and perfectly reasonable that he would have plans that can't easily accommodate phone contact with a client. So not about you, or about him doing something wrong just that he can't be available to you when you want him to be.

I don't know what you mean when you say you wanted words of support or comfort so can't make any assessment about whether his response was reasonable or not but it seems fair for him to want to talk about it in session rather that risking missed communication by text or phone. It's not uncommon for clients to cancel sessions if there's been a rupture, I'd simply text that I wanted to keep the appointment ans talk to him about it there.
