Try to put yourself in places where you'll find people (including women) that share your interests. You do have interests, don't you?
In your OP and other posts you don't say anything about yourself, except what you lack. Are you interested in mathematics, motorcycles, or music? Do you play poker, bridge, or Monopoly? Are you a geek, or a runner, or into meditation? Do you like museums, baseball, or old cars? Fishing, hunting, oil painting? Church, temple, or mosque? It is always easier to start up a conversation with someone when you have areas of commonality.
And don't talk about your ex!!
I went out on an arranged blind date once, and all the guy could talk about was his ex. I know that this should probably go without saying, but you may need to hear it. By the end of the evening I felt like I knew her (the ex) pretty well, but I didn't know him at all!
