I’ve been a side chick for over 5 years.
I didn’t know he had another girlfriend until about 2.5 years into the relationship. Keep in mind, by this time I was already so deep in love with this man and thought I’d marry him. Lost my v-card to him and everything. We met when I was young and he was a bit older and the effect he had on me was insane. To cut a long story short, I was so in love with him already that I couldn’t bear the thought of being without him. So I stayed. Fuck me, I know.
