Ex Co-Worker Still Text Me and My Man Has A Problem With It!

Leo and Rebecca Buzz Question - The other day I got a text from an EX-Co -worker who use to text me all the time when we use to work together. My man had no problem with it. BUT NOW THAT he no longer works with me he has a problem with it. He said he ain't got no reason to text you now that he don't work with you. What's the difference? I told him that's rediculous. Right?
