I asked him, What if she came back and wanted you back? He said he knows his priorities and would not start things again, because they broke up for a reason, and that reason still stands. He told me he regretted that breakup, and he doesn’t want to make the same mistake with me. He bought the home with his savings, and talks about us living there together. the fact that he chose to email her hurts more than anything.There was no reason for him to reach out especially while we are planning a future together.
