So I think I have Chlamydia. Waiting a few days for the test results but for now lets just assume I do have it.

How do I get my gf to admit that she slept with someone else to give it to me?

I was going to tell her that if she tells me the truth I will stay with her (bluff) to see if she gives in for the sake of keeping me. Do you guys think this would work? Or does someone have a better way to manipulate the truth out of her.

The only other possibility is I got it from this inexperienced girl before me and my current gf started dating. But I think it's highly unlikely and haven't slept with her since. I intend to ask her to get tested as well if I come back positive, but again there's no guarantee she will be honest if she has it, so I was thinking I would twist it and say I think I gave it to her (so she can eagerly claim victim status if she comes back positive)
