The internet has made it possible for anything to happen.
A person can be in love with a physical person but still look for "virtual love" online.
However, you can easily tell if your partner is looking for love online without infringing their privacy.
1. Use social media
The availability of social media has made it possible for people to connect.
Probably you even met him on Facebook or Telegram.
Now you can tell if he is seeing someone else on dating sites depending on the pictures they like, the comments they give and the forums they ask to join on Facebook.
One reason I don't like Facebook is that if you want to join a group, it will notify everyone including your wife that you asked to join "Secret Love Group" as long as she is a member.
2. Check if he has installed Dating Apps on his phone
The smartphone era has made it possible for people to date online.
A person can install a dating app on their phone.
To tell if he is still using them, of course, he will have at least one dating app installed on his phone.
This is a signal that he is interested in other women online.
3. Check his browsing history
Browsing history on a computer is the worst thing the internet brought because you can be caught of any wrongdoing.
If your partner is visiting these sites, the information will still remain on the computer because no one bothers to delete the browsing history.
