<human>: Hi everyone. 

So basically my best mate had unprotected sex at a party with another girl I know about 2 weeks ago. She has confessed that there is a chance that she could be pregnant. Now I'm not sure exactly how all of this works but she said she has to wait for the 3 weeks(??) to confirm the pregnancy and find out the father.  Should also add that she has also had sex with several other men recently. The two currently have no contact for a few reasons, and he has no idea that she could be pregnant. Should also say that she is still tossing up whether to have an abortion or not. I know that he is not in a position to be a father at all, and does not want a kid.

Now the problem is whether or not to tell my friend. At the moment only me and this girl are aware of the situation. Now if I was in my friends position I would want to know immediately, but he is in a pretty bad state mentally at the moment. He has serious anxiety issues and they have not been good recently. I am afraid that by telling him that he could be a father might push him over the edge. I'm not sure what I should do right now. Please give me advice on what I should do.

Can you give me a shortened version of the text?
<bot>: friend had unprotected sex, he doesn't know the girl could be pregnant but I do. Should I tell him, when I should tell him, and how should I tell him.
