Personally, I don't think setting a 'curfew' on each other is always a bad thing.
For example, if he cheated on her at the beginning of the relathionship, she has perhaps agreed to trust him again as long as he accounts for his time. ( A fair request) and perhaps he feels that if he has to account for his time, so should she.
You used the word 'curfew' but is that what is really going on? Perhaps it is an easier word to say than a long winded sentence 'in order to regain the trust from my boyfriends mistake we have decided to be accountable to each other for how we spend our time.'
Our perhaps they have a lifestyle where they are busy in the morning so the curfew is to make sure they get enough sleep for the day ahead. There is not enough information to tell
However, you are obviously fed up with being her sounding board and don't feel like she is making the best choice. For that, you do have a right to your boundaries. You can either tell her you no longer wish to hear it, tell her if she wants your honest opinion that is exactly what she will get (be prepared to loose the friendship over it but then is she worth being friends with if she shoots the messenger after asking for the truth?) or find some liveable compromise.
Parents dictate curfews, not spouses. Spouses let each other know clearly what they need, and then try in good faith to meet each other's needs voluntarily, using mutual self-sacrifice, communication, a sense of humor and affection and, when necessary, compromise. There is a very big difference.
Your explanation of how the two friends might work out this situation is a good example of how adults set boundaries and make joint decisions. Even spouses get to set and enforce boundaries, after all.
This kind of thing doesn't just come up with offenses like infidelity. It comes up with how to use money, how to take care of our health and manage our careers, how to determine the level, frequency, and division of routine domestic chores, how to manage outside friendships, how to balance hobbies and entertainments that are not held in common, and so on. The list goes on and on.
