They'd call him paranoid, insecure, and controlling, but he was just drowning, suffocating, and afraid of the pain of losing everything, again and again and again, let down by those he cared for most. Lied to, played. Everytime he let someone in. He'd always be the "bad guy" if it meant protecting his heart from that old abyss. I guess people think they are entitled to being trusted. Go earn it.
Trust issues are not a reason not to love someone. Trust issues are trauma leaking through the smiles.
