Genocide and Pacifist explain it a bit why the main character and monsters want to leave. Also, the Underground is a terrible place to live. No sun, no stars, no moon and it's over crowded. Things in the Underground rarely change, and when they do, it's for the worst.

A suicide option would actually be REALLY awesome. Not sure I'd complain about not having one, but it would be a nice addition.

The games DOES give you the option to stay with Toriel, just that nothing will happen if you do. And tbh, what is there to do? If you stay with Toriel then all you can do is stick with that choice until you realize it won't get you anywhere and you choose to leave. The game isn't necessarily forcing you to leave, just that there's nothing after if you stay.

Toriel stops talking to you because 1. Her phone got stolen by a dog and 2. Knows that talking to you or seeing you again might make her want to bring you back. She DOES appear again in Pacifist mode though.
