A little experimentation and tweaking should get you set in just a couple of minutes.
It should work by disabling all but your phone number on iMessage, but you may need to disable everything on your Mac as well. This should force messages to communicate with only your phone number.
SyncMate Expert allows exporting messages from your Android to your Mac in. You can also send messages to multiple recipients at a time.
Simply tap the email addresses that are checked to disable them. With the Expert version of SyncMate you can send text messages right from your Mac (your device should be connected to Mac) - just click New text (SMS) button. This is probably your apple ID, but can be any other email address you've specified. Look for the menu option heading that says "You can be reached by iMessage at:", which has your phone number (checked by default) and the email account you configured when you initially set up your iPhone. Scroll down to "Send and Receive" and tap it. Tap "Settings", then scroll down to "Messages" and tap it. Unchecking these will disable the ability of Messages.app to receive those messages you wish to send only between mobile devices. Selecting "iCloud" from the options on the left side of that screen will show the email addresses you specified and your phone number.
Under the "Accounts" tab, you will see all the accounts you've set up to use with Messages, including iCloud. Access your preferences by going to the menubar and clicking Messages -> Preferences. You can disable Messages.app's ability to receive text messages on your Mac: First off, make sure both the computer and iPhone have been set up to use the same Apple ID. You have a couple of ways to configure this.
