Annoying iMessage

I have a nexus4, but many of my friends have iPhones. Mass texts from their phones have been changed into group messages due to I message. Great feature but unfortunately there is no imessage for android which means I receive a text for every reply to the group chat. Used to not bother me as much but as of recent its been getting very annoying. Just wondering if there is any way to opt out of all those notifications.
