Why isn’t it fair?
Sorry to tell you this but you don’t get any medals for doing the right thing, for being responsible and actively participating in life. It doesn’t work that way.
You are there, actively participating in the hell you live in. Why are you with him? What does he bring to the relationship … anything other than chaos, a sense of entitlement?
You are not a victim, you are there, allowing yourself to be treated as you are. And then you are pissed cause he has fun … look at his life, where is this going to take him any place with security, with wonderful, with promise …
Look at yours, how much longer do you think you can live day in and day out being treated as you are? What do suspect might become of your spirit, your promise for the future with him.
