Forward imessages from iphone to email

Does anyone know how to forward messages that are all from one person from your iphone to your email or PC? I just would like to read over every single conversation that I have had with this person since I bought the phone. I know that you can check each individual message one at a time, but I was wondering if there's a quicker way to do this because I have had the phone for about a year and have a lot of messages to forward.

Sorry, but there's no easier way, you'd have to send them one by one.
Although, you could take a screenshot of the page and do it that way.
