There are some people who might have an underlying motive to be mekarev you.
There are others, however, that don’t have such a motive. They allow you to make your own choices, but they want you to make an informed decision. Learning with them will allow you to gain the information you need to make an informed choice. I say you should do it, but be very careful about who the person is. Being pushed into something is horrible. Being accepted and cared for is great.
Why worry about your friends. Your friends don’t have to know that you learn with someone for say an hour a week.
