i don’t know if this works with your timeline/history for her, but i’ve been looking for his ex from 2013-2015. they were briefly engaged despite having a super toxic, fighting all the time relationship, and they broke up for good because he was convinced she was cheating on him (the reality of that could go either way). if not! maybe a brief fling last year with intense dating rumours but really they just had a casual thing and hung out a few times?
