If you have been seeing her for 5 months and are sexually intimate, why didn't you have a discussion at the time the condom broke?
Communication is a huge part of a relationship - while I think it's great that you are coming here to ask questions, it seems most healthy to have this discussion with her?
Why are you bothered that she did not tell you? That part I am unclear about.
I'm sure she took it as a precaution...good thinking on her part. You don't want to be a daddy just yet...do you? There's no reason she needed to tell you anything about it. As stated above...it's her body. You've been dating all of 5 months...far from a committed relationship. I wouldn't worry about it, you should be thankful she cared enough about the future of both you and she to make that choice. Practicing safe sex is a responsible thing to do, just be careful not to pop anymore condoms.
I agree with mags59. It's her decision and a good one. I don't know what kids are doing having sex at 16 but at least your using a condom. I would drop the subject and forget about it. Keep having safe sex and buy a better quality rubber.

Why should she have to tell you? It's her body, her decision not to get pregnant, especially since you say the condom ripped. Unless you're married, it's her business, period.
maybe because she was scarred. why dont you ask her?
