Yeah, Paulo, I was totally in your shoes.
My husband was cheating on me, I eventually had the balls to leave him. I was SO pissed off at men and started not really truly being able to trust any of them. I would meet guys and date them, I'd realize I couldn't feel anything for them so I'd blow them off callously.
I was angry for such a long time.....it took me about a year and a half for my anger to get down to a level where it didn't affect my perceptions of men and relationships. I can't tell you what changed.
I think you have at least recognized your behaviour, which is a start. Just start asking yourself what is motivating you to be this way. You're allowed to be angry, but don't let it consume or affect your life. Maybe just stay away from women for awhile until you feel you're a little better sorted out.
