Not receiving some of iMessages from only one person, help!

[Monstah11]

For some reason the past month or so I haven't been recieving some of my girlfriends iMessages. I keep getting yelled at because she thinks I ignore her texts but I don't get some of them. And it's only some of them I recieve most of them. It's only at the beginning of a convo not in the middle of one or anything. She sends from different locations with service so I don't think its a service issue. It's only her too I haven't gotten any other complaints about it. It has even happened on a phone call she said she called but my phone didn't ring. She says when she sends that it says delivered, but they are not. This is starting to get annoying and pretty odd it only happens with her, I have the iPhone 6 she has the 5 both with latest update. Please help
