[iMore Question]

So if I surf the net, all my surfing and history shows up on the MacBook Pro. My IM and text messages end up there too.

Welcome to iMore! This is happening because both devices are sharing the same Apple ID. I recommend creating a separate Apple ID for one of the devices (see the link). Otherwise, you'll have to sign out of Messages and disable Safari in your iCloud settings so that it isn't pulling over all of your browser history.

It happens because either you are using his iCloud account or he is using yours or you have a shared account. You can fix the Messages issue (texts) by going into Messages on the MacBook Pro. Then under preferences go to Accounts and under the you can be reached at look for your phone number or email and uncheck them. Then for the browsing history go to System Prefs on the Macbook Pro and iCloud look for Safari and uncheck it. If you both use the same iCloud account then I would suggest one of you setting up a new account. As an example my wife and I both have separate iCloud accounts but we both use my Apple ID for purchases so we can both share.
