Perfect. Too many relationships stay together that should be broken up. In Canada we have something close to 50% divorce for the "young" (under 30-35 i guess?). If they are divorcing, they were not a couple that should have endured courting... be mature, do the right thing and dump your BF/GF so you can marry someone that you won't divorce. OR, ask the really hard questions and be calculating with your decision, don't let your heart direct you toward the 50% stat.
Side note, how many couples will secretly use this tool to find out their partner's fidelity?
