I'm scared of repeating my parents mistakes?

I'm in a similar situation. My mom has been married 4 times!! I was really worried when my hubby asked me to marry him. I was scared that I would be like my parents. But, after 5 happy years of marriage, I know that I am able to make my marriage work and one day you too will meet somebody that you can trust and love. I actually live everyday of my life trying not to be like my parents. Sometimes I check myself and say "what would mom do?" and then I do the opposite. Good luck.
