2. He Protects His Gadgets More Than Normal
If your man gets very sensitive about you touching his mobile or PC, it could be a signal. It could be that he doesn’t want to get caught red-handed with e-mails or SMS messages, so he may be protecting his devices from you.
This may be a signal that he’s being unfaithful. If he doesn’t do this sort of thing at the beginning of your relationship, then there may be a problem so watch out for such changes.
