This same time of pressure to produce exists in a lot of work environments as well. If it's supposed to be a "pair" you might find colleagues that also consider one an anchor. This is why I prefer to make it more informal, or consider it mentoring. If the other person knows his goal isn't to produce code, but to get you to produce code, the dynamic is very different.
If you find the other person is also unwilling to mentor you, then that's a whole other story.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
