If you guess wrong, you can ignore my answer.
The suggestions are as follows
1. Ask your mother if the situation is what you think.
2. Communication is the prerequisite for all communication to continue. If you feel embarrassed, you can communicate by phone (I personally feel that written social communication sometimes fails to convey the meaning).
A mother's life should not only revolve around three meals a day. It is often said that parents should learn to let go, and as children, we should also learn to be independent.
4. What's the boy's character? As a classmate's project, he can communicate with his mother.
I think the subject is obsessed with the possibility that students may become their stepfathers, which is a bit unacceptable in common sense, but understandable in reason. Just like the third suggestion, parents should also have their own lives.
Off-topic, the subject mother should be very attractive.
The above is for reference only.
