Is there a way I can save all of my iphone text messages to my pc?

I'm a sentimental guy and don't really want to delete any of my messages with my girlfriend. I would like to save them in case we ever want to reminisce. With that being said, is there any app I can download to my pc that will let me save all of my messages?

Yeah through icloud get i cloud on your computer then take pictures of the texts then upload them from your phone to icloud
