We weren't in a serious relationship but "dated" for about 7 months. She was basically someone I would go out with to non single events and we would hang out at her place. We would spend time together about 3 times a week at times. We had fun and would be somewhat affectionate a lot of the time. I miss her once in awhile. I broke things off because the situation began to feel toxic to me. I also discovered I wanted either a serious relationship or nothing. Is it normal that I misss her now and then? even though i know we wouldn't be good for each other.
