Boyfriend help

Madelyn
Okay so my boyfriend of 5 months has started to not answer my texts. I understand he has a life and does not need to devote all of his time to me. I texted him yesterday and asked him if he wanted to do something. I still have not gotten an answer back yet. I understand if he was doing something but when I know he got the message and has read it cuz he has the thing on the iPhone so it tells me. I am starting to get really annoyed. What should I do? Not trying to start anything with him this is just annoying.
