When we have been hurt there is also hope. My guess is that the pain you felt from the breakup is fueling hope for a new relationship. This is natural, and the fact that you feel this pull to be with someone is natural. Yet I can hear how difficult of a situation it has created.
One way to begin dealing with this is to practice brief conversations with women that are designed for you to have a beginning, middle and end. In other words, initiate a conversation with a woman while you are online for coffee or groceries and practice your endings: “It was nice talking to you;” “Enjoy the rest of your day;” etc.
When you learn to ski, the first thing they teach you is how to slow down and stop. When you learn to ride a bike they teach you how to brake. You need to practice brief encounters so that every one doesn’t get you too involved.
Wishing you patience and peace,
