I fucked up

So, I have this female friend who, since we've started talking, has gone through like, 4 bfs. I noticed she was starting to talk with another guy and I just couldn't stay silent.

So.... I asked if I could talk to her, told her my concerns, that I didn't want here to get hurt how I did and that maybe she should try taking more time between relationships to be by herself.

She.... didn't take it nicely. She just replied with "I wish you hadn't said anything" then went to bed.... what do I do????
