Should I text him and ask him how his weekend was?

Anonymous
I recently started emailing a guy that I met on a online dating site. We exchanged numbers and texted a few times. We talked on the phone on Saturday Night and he said that he will text me either on Sunday or Monday. He also said that it will probably be more like Monday because he will be very busy on Sunday. Well, he never texted me or called. Would it be OK to text him today and say something like: Just wondering how your extended weekend was? I want to let him know that I am interested in getting to know him but I don't want to seem desperate either.
