I know it sounds bad but love just happens. Love will happen wherever it can happen, like murphy said or something.
The worst part, the woman he cheated on me with was no other than our mother.
A mother is supposed to be someone who is always there for you. Well she was there for him at least. Now how can I ever trust my own mother again? She's supposed to respect my dating life. Like yeah, so it's my brother, but still? I thought she would understand... I'm just so heart broken guys. Am I the asshole?
