I still cant help feeling we were meant to be :[?

You fell for the oldest line in the world, I'm sorry to say. "Open relationship" is a code word for I want to see other people. You may think the sun rises and sets on him but he is obviously not the person you imagine him to be. When you give a person a mantle of perfection, sometimes, you do not notice that there are rips in the cloak you put on them. He is a person, not a god and he is acting like a 21 year old who isn't ready to commit to one person forever.
