she sounds really great and i love what you've got for her, we can for sure say they were good friends and who drifted apart before circling back together again in high school. it could've even been born from some party, a project that they had to do together or an after school activity where they ended up hitting it off again and started dating. i figure it would be a few months to a year tops because fickle high school! i'm still trying to figure out some personality specifics from high school but the fact that her house was so strict is definitely a good reason for her to want to do some normal teenage rebelling, meanwhile his parents were split up and while his mom's house was just a little more strict his dad's was a free for all so he would know how to play both sides when he wanted to do certain things. it could've ended after high school because i thinkkk i'm going to say he went elsewhere for high school at least in the beginning so that could've been a big reason why, on top of potentially starting to fight more with end of the year stress or just not seeing eye to eye the way they used to/we can amp up the social circle thing where they were just being pulled in different directions?
