Signs It Really Is You, And Nobody Else, Messing Up Your Relationships
You presume monogamy
Even if a guy was going to say that he wanted to be exclusive with you if you just presume you’re exclusive before it’s discussed (and yell at him for not deleting his online dating profiles yet) then he’ll want out. He won’t tell you it’s because you’re possessive, of course, because that will probably cause you to angry-stalk him.
