Is it possible my text messages aren't getting sent?

Hey guys well I'm just wondering what's up cause I got an iPhone 6 and well there's been 2 occasions that have led me to believe that sometimes my sms messages don't get sent out. My reason for believing that is because I don't a message back from that person. So do y'all think it's possible that they really don't receive my messages or you think they just don't wanna reply back lmao when I told one of my friends about it they told me they had never even gotten the last message before. I just wanna y'all think it's possible since there's no way for me to tell when my sms messages actually get delivered, that they truly sometimes don't get certain messages or that they do get em but just ignore me? Haha
