Is this fair to ask of me?

Hey! I asked my husband for a divorce yesterday. He said he would move out and do what I need, but he would like to stay married for his citizenship for the next three years.

At first I was OK with that. Like, I had promised to fix him papers before we grew apart and then I ripped it out from under him.

But then I realized it’s a felony and I could go to federal prison for lying to the government.

I told him I was uncomfortable staying married for citizenship because I didn’t want to get caught and now he’s saying I’m this huge bitch and I never truly cared about him and if I really wanted to help I’d just do this for him.

Now I’m conflicted. I do care still and I want to be able to help. But is it worth it for the risk? Not to me, but I feel torn anyways. Was this fair to ask of me?
