If you've been dating a woman a while (5+ months) and you want to find out if she's worth investing in still, create a chadfish account and then see if she's on tinder. If she is, superlike her account. If she adds you then you at least know that she's not worth investing anymore time or energy in.

Thus, at least you can have the last laugh by getting her to meet somewhere as the chadfish persona then not showing up. Additionally you've now got evidence that she's a cheater and can show her friends & family if she ever f***'s with you again. This works better if you live in a smaller town where the number of tinder users is smaller but take a crack at it. Cheers guys!
