Text my girlfriend, but don't call me back.

Everyone upstairs has a point, and that's the truth. If you don't reply, it means that the other party may have a new situation. At least she doesn't have any reaction or thoughts about you. You should take the initiative to find her, whether by phone, by asking a friend or in person, to find out the situation, or forget it. If it doesn't count, it seems that it will.

I sympathize with you, so don't wait for a reply passively. Take the initiative to understand the situation and think about solutions. Maybe when you know the situation, you will have a destiny in your heart, whether to go or stay. Don't escape.
