This is a tough situation. It could be that she's having some emotional outburst or there's a misunderstanding. You need to assess the situation carefully. If you think it's safe, try to reason with her. Maybe she locked you up because she was afraid you would leave or something bad would happen to you. But no matter what, your safety and freedom are important. If you can't resolve it on your own, seek outside help as soon as possible.
You could try reaching out to her in a friendly way and ask her why she's still watching your stories. But be prepared for any kind of answer, including a cold one. Maybe she'll be honest and tell you that she misses you a bit, or she might just say it's out of habit.
Well, it's a tough situation. In a light novel, things might seem more dramatic, but in real life, you should assess your own feelings. If she cheated, it's a serious betrayal. You might want to distance yourself from her for a while to clear your head. Think about how important the relationship was to you before this happened. And also, don't blame yourself. It's her actions that are at fault.

I'm deeply sorry that my actions caused all this.
I really regret not cherishing you.
I want you to know that I really want you to come back to me
I'm sorry that my behavior has disappointed you.
I promise I won't make the same mistake again.

No, you don't need to be worried. It's probably just his way of staying updated on your life out of simple curiosity. He may not have any malicious intent.
Well, it's a really difficult situation. You should think about what you value more in a relationship. If loyalty is very important to you, then it might be hard to continue with your girlfriend. Regarding your friend, this is a serious betrayal. You can confront him and ask for an explanation. But keep in mind, whatever you decide, it should be for your own well - being. You don't want to be in a relationship or friendship that makes you constantly feel bad.
This is a very inappropriate and unethical situation. You should firmly say no to your girlfriend. Such behavior goes against moral and ethical norms. You need to have a serious conversation with your girlfriend about what is acceptable and unacceptable in a relationship.
First, you need to be completely honest with her. Admit what you've done without trying to make excuses. Then, give her some space to process her feelings. You could also write her a heartfelt letter explaining how sorry you are and how much you value her. For example, you can list all the things you love about her and how you'll never make such a mistake again.
Just let her be. Reading fanfiction is a normal hobby. Maybe you can also encourage her to join some fanfiction communities where she can discuss with other fans. It can be a great way for her to make new friends who share the same interests.
If you find out your girlfriend is getting too close or involved with your friends in an inappropriate way, first, you need to have an honest conversation with her. Ask her about her intentions and how she feels about those relationships. Don't be accusatory at first, just try to understand. Then, also talk to your friends. Let them know that you're not comfortable with the situation. If it continues and it's clearly unethical behavior, you might have to consider ending the relationship for your own well - being.
