I still don’t get this “we are both girls so it’s not serious / it can’t go on” trope. Lesbian (or gay) relationships are not a thing?
And if the motivation behind it is “I’m scared of what could happen”...well, it’s normal, but why don’t just talk to your partner about it instead of running away?
Seriously, it’a ALWAYS this dumb bs...at least find other motivations to make them break, authors.
