Feeling confused

Hey y'all I really need some advice. I have an amazing husband and two beautiful daughters. Yes my relationship isn't perfect we fight we yell but we love each other. The last few nights though I've been dreaming of my ex. My first love and heart break. I can't get it out of my head what should I do ignore? Talk to him? Talk to my husband? Ugh I'm so lost and confused!!! HELP PLEASE!!!!!
