5. Try to make a profile using their email

This one falls into the same category as the “forgot password” trick. To try this method, you need to know your partner’s email address. After that, you can go to the online dating website that you wish to investigate and go to the signup page.

Start creating a new account and using their email. If the website tells you that there is another account created using the same email address, this means they have an account. If you can go to the next page and continue the signup process, your partner doesn’t have an account on that website.

Again, remember that even if they have an online dating profile, that doesn’t mean that they are using it right now. Maybe they have used it in the past, even before dating you.
