Pretend to be sick and test whether he is sincere.

It is not a good thing for you to pretend to be sick to test whether he is sincere or not. When two people are together, it is most important to be honest and communicate with each other. Whether he is sincere to you or not, you should feel it when you get along with him at ordinary times. Why pretend to be busy at work? I may ignore you occasionally. I think if you love him, you should also understand him. Your feelings are two-sided. I wish you happiness!
