I've Made Mistakes In Life

Ive made plenty of mistakes in life, mostly small ones.. but the biggest of all has to wasting so many years on someone who i knew wasnt right for me, not sure i ever loved him..i just didnt want to be alone so i put up with substandard treatment for over 13 years. I dont want to make the same mistake again.. but with the same fears and insecurities fuelling me, i feel its a possibility.
