How to go about distancing yourself from people?

[Sphinxi]

Before I ctb, there are two people whom I need to distance myself from: both friends at my university.

One I am just friends with, we are fairly close, we see each other a few times a week and have a class together. He is very funny, and we read a lot of books together. He knows I use this forum, and that I am a suicidal person.
The other I am more than friends with, and I am more concerned about him. He cried when I told him about my suicidality. He has grown incredibly attached to me very quickly. I think he wants to marry me. I'm not sure how to push him away so that I can ctb in peace.
This advice wouldn't be very specific to me, as this situation isn't unique: how do I push people away so that I am free to ctb, and so they won't be harmed?

Slowly decrease the time you spend with them and talking on the phone with them. Every other day, increase the time longer. They should start getting used to the lack in communication they have with you.

As far as harming them, if you're talking about the breakdown or sadness they will feel when you ctb, that will be inevitable. It's going to happen.

I appreciate the advice. I know it will hurt to some extent, but I am just trying to minimize it over the next week or so. Maybe I could lash out at them?
