The best way to let go of the past is to focus on the present and the future by-
-Keeping busy with work
-Finding & then focusing on what your passionate about in life, it could be a new job in an industry you've always wanted to work in or it could be a new hobby.
-Outline goals that you would love to achieve that don't have anything to do with a man but have everything to do with the very special and unique person that is YOU xo
Focusing more energy into yourself, your career, financial goals etc is a great way to let go of the past and is a great start to getting excited about where you want to be in the future & any future man that comes into your life can just be the icing on the cake. Love and best wishes xoxo
