Hi,I'm Jules, a LPC,I am reviewing your question now, and will post back with your thorough reply briefly :)
I am happy to assist. I am curious prior to beginning. Was there a typo at all in the statement that you quoted from your ex boyfriend?
Would you mind to retype it so that I fully understand the statement :)
I think that basically what he was saying to you, if I am interpreting this correctly, is that if you are calling off the relationship at this time, he wants you to know that he wont be coming back into your life with the same role that he once had. I think he doesnt want you to call him up or reach out to him if you have something that you need support with. Depending on how recent the breakup is, he may be saying this to you because he was defensive or hurt. His ego may have been hurt because you broke up with him. I think that feeing some anger from him is a normal part of the grieving process-- actually it is the second phase that many people dealing with a loss go through..... Maybe that helps. I will wait for your response :)
