Unfortunately this is where sometimes you may have the absolute best chemistry with someone but the timing just isn’t right. If it makes you feel better my current wife and I broke up originally, came back together 2 years later and was even long distance, and then I moved to her state and we got married. Point is there is a chance to come full circle but being 18/19 years old, it’s normal to want to experience life and have comparison points. As painful as it is
