Yeah man, take time for yourself. Something similar happened to me not too long ago, becoming single. I was always in a relationship, but now its great to be single and DO WHAT I want, not what she wants. Just take the time for you and accomplish your goals, believe me you will be satisfied more then she could ever satisfy you. And when you take care of yourself, accomplish your goals, you will find a special someone and she will be so much greater then your ex.
