am I a bad person

Lissa • Mommy to Remington 💙
So my ex and I dated 3 years and I broke up with him almost 6 months ago for other guy who treats me better and how I should be treated. My ex was mean to me and treated me awful. To this day I still think about him at least once a day and I get a little sad about the break up. Why is this? Am I a bad person? 😭 I don't want to feel like this anymore.
