This victim role you're pushing yourself into is a defense mechanism and a poor one at that.

Correct way to deal with this is to get your self-esteem back on track. You're a man, approach this situation like one. Open your eyes to what's good about you, what's attractive about you, what you love and like about yourself. Once you remember that you're a good man with a lot to offer, once you remember that you like yourself and want to see yourself succeed - your inner resources will naturally go towards recovering from this correctly and moving on to something better.

How we think about things matters a great deal. In this case it will be a difference in total misery for a long time, or a quick recovery with a relationship with someone better on the horizon.
