I would trust you too.
For the longest time I believed that I was a good person: honest, kind, trust worthy, the whole shebang. This was true until I cheated. I had no intention of doing so, but once upon a time I did. Shit happens, and no matter how rational you are, when emotions come into play there is no room for rationality.
So, don't you see? I, a "good" person, am not necessarily always good. So how can I trust that You, a "good" person, won't be just as bad as I have been? Everyone is flawed. Everyone sins. Everyone fucks up. I have no reason to trust you or anyone. Whether it be intentional or not, pain will stab me in the heart, and there is nothing I can do about it.
P.s. This all started because my boyfriend is going to a good bye party for his Ex Girlfriend, whom he used to be In Love with. That scares me a bit, but please share what you think about this situation.
