Overracting or not?

My boyfriend and I are long distant and I usually just ask for at least one text a day that's all, more would be amazing but just one text makes my heart full. He didn't text me for two days and today he texts me saying "sorry babe I was sick for one day" that doesn't excuse the two days he didn't text though.. I don't wanna make this a big deal but he also didn't text me for one day and brushed it off by just texting me the following day (different incident but fairly recent btw) Should I let him know this isn't okay? That he should at least tell me he isn't feeling well and wants to rest instead of leaving me worried.. Am I being reasonable ?
